I wonder if anyone can help me please...

I have been given a CD of 30 songs, all MPEG4 Audio files and they are on a CD-R , 52x speed and the disc holds 700mb.

Today I converted all the songs to MP3 and now when I burn a CD-R of the same size and capacity, Windows Media Player is looking to burn them on 2 discs. I've looked at the file size and the MP3's are smaller in size than the MPEG4. I wanted this to play in my car and on my Pure Cdplayer but neither players support MPEG4's

How can I get them onto 1 disc? Sorry if this is the incorrect forum

Re: Mpeg4 to Mp3 query

What's the total filesize for all 30 MP3s?

What MP3 settings are you using when you convert from MPEG4? (bitrate, mono/stereo, etc)

A 4 minute song will be about 4-6mb in MP3 format, so a 700mb CD should easily be able to hold 30 MP3s even if you have all the quality settings on maximum.

Thanks for your reply

The total size is 106MB. I used M4a to MP3 convertor and the settings are at 44100 freq, stereo and 128 bitrate. I didn't change them, they were set at that already.

Re: Mpeg4 to Mp3 query

128kbs gives the same kind of quality you'd get from a tape cassette recording. If the original MPEG4 files were recorded at 128, then stick with that setting as increasing it won't improve the quality.

If the originals were higher, then increase the MP3 to match. 192 or 256 will sound better, and 320 will be CD quality.

If the total size is only 106mb for 30 songs, you should be able to fit about 200 similar-length songs onto a single CD, so I've no idea why Windows Media Player is trying to create 2 CDs, unless it's trying to create an audio CD instead of burning the MP3s as data.

First, go back to your converter and see if you can increase the MP3 settings from 128 to 256 (or as high as the original files). Then, instead of Windows Media Player, use another program like CDBurnerXP to create a 'Data Disc' which burns the MP3s as data files, not audio files.

Re: Mpeg4 to Mp3 query

Thanks very much for your help! I followed your instructions and it has worked. All MP3s are on 1 disc. I had no idea of the bitrate of the original MPEG4's but I set it to 320.

I have another query but not sure if it is a hardware related query.....we have 2 disc drives. 1 is a cd/dvd burner, the other is a cd/dvd player. For some reason, the autoplay is no longer working on our player. I have tried following instructions I found online but nothing seems to fix it and its real annoying now. Would there be something wrong with the player? It plays if you manually open a file.

Re: Mpeg4 to Mp3 query

If the drive can read and play files, then it's not faulty, but there could be a problem with a registry setting that is preventing the autoplay feature from working.

See if these 2 articles help:

http://www.windowsitpro.com/article/windows-xp2/windows-xp-autoplay.aspx

A while back, my Windows XP CD-ROM and DVD AutoPlay feature quit working. I read the Microsoft articles "The AutoRun feature or the AutoPlay feature does not work when you insert a CD-ROM in the drive" and "The AutoPlay Function Does Not Work and the Current Media Does Not Appear in My Computer When You Insert a CD or DVD" , but neither article helped me solve the problem.

Finally, I tried inserting a CD-ROM, selecting My Computer, right-clicking the drive that contained the CD-ROM, and selecting Properties. I clicked the AutoPlay tab and selected the Select an action to perform option, then double-clicked the program I wanted to use to run the CD-ROM. This action launched the program on my CD-ROM. Note that simply highlighting the program you want to use and clicking OK or Apply doesn't work; you must double-click the program and force it to launch on the CD-ROM or DVD in the drive. My CD-ROM then ran automatically, using the program I associated with it on the AutoPlay tab.

Method 2: Make sure that AutoPlay is turned on

Important. This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click the following article number to view the article in the Microsoft Knowledge Base 322756: How to back up and restore the registry in Windows

The AutoPlay feature may not be turned on. To turn on AutoPlay, follow these steps:

1. Click Start, and then click Run.

2. Type regedit, and then click OK.

3. Locate and then click the following registry subkey:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\CDRom

4. Double-click Autorun and see whether a zero or a one is displayed in the Value data box.
* If the value for Autorun is 1, go to step 5.
* If the value for Autorun is 0, right-click Autorun, and then click Modify. In the Value data box, type 1, and then click OK.

5. Locate and then click the following subkey:
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer

6. Double-click NoDriveTypeAutoRun to see its value. If the value is 0xb5, the AutoRun feature for CD-ROMs is turned off. To turn on the AutoRun feature, follow these steps:
a. Right-click NoDriveTypeAutoRun.
b. Click Modify.
c. In the Value data box, type 91.
d. Select Hexadecimal, and then click OK.

7. Exit Registry Editor.

Note: Before testing to see if this has fixed your problem, you might have to reboot for the registry edits to take effect.

Re: Mpeg4 to Mp3 query

I tried the first one and it didn't work. The other one, I found before and went through it step by step and it didn't work either.

However, I've noticed that the actual burner doesn't autoplay either. I had incorrectly assumed that it was working because I had Windows Media Player open and as soon as I inserted a CD into the burner, it automatically played. This does not happen with the player though. It used to be the case as soon as a CD was inserted to either drive, the Autoplay wizard would appear and you had to select what you wanted to do, ie play or copy etc.

When I go to My Computer, and right click whichever drive the CD is in, it recognises its an AudoCD and within properties of each of the drives, the autoplay tab is sitting at Music Files and the prompt me button is checked. If I select an action to perform, no list comes up. If I change the selection from the drop down menu to Music CD, a list comes up to choose from, ie Play Audio CD from Windows Media Player etc etc. However, there are a couple of items above those choices that aren't properly visible. Here is a screen shot if it helps.

I hope this makes sense!

Re: Mpeg4 to Mp3 query

Have you tried clicking the 'Restore Defaults' button in the Audio CD Properties window?

If that doesn't work, run this Autplay Repair program: http://www.softpedia.com/get/System/OS-Enhancements/Autoplay-Repair.shtml (freeware, safe to use)

Re: Mpeg4 to Mp3 query

I clicking the restore defaults button and that didnt work.

I downloaded that software and immediately found out that the 2 rogue entries were Nero which I had trouble with previously and had uninstalled a version I had of it. Within the Autorun Cleanup, everything is checked that has appeared. I can't remember if the Autoplay stopped working then but it's still not working like it should. I have inserted a shop bought CD into both burner and player and nothing happens. I still don't get the Autorun Wizard to choose what I want to do. The CD will still start to play if I double click the disc drive which the CD is in.

Re: Mpeg4 to Mp3 query

I'm out of suggestions, sorry. Start a new thread in the XP forum with a reference link back to this thread so the person helping you can see what's been attempted so far. Good luck. :smile:
