Recently i bought a new DVD RW for my computer as the old one broke after 3 years of use.

Having only had the new device for two weeks i am having DVD playback problems with it.

Have been using without issue to play dvds but when i came to use it today the playback was slow and choppy.

Have already checked IDE settings and they seem correct, and cant understand why the playback would have changed overnight with only two weeks of use.

Would like suggestions as to solutions.
To cut out some needless responses i have already checked the following

1. windows tutorial
2. tried on several different media players
3. tried playing on ubuntu OS aswell, but that failed aswell.
(although i suspect there could be any number of reasons as to that one and i dont really count that as conclusive evidence of device damage just yet)
4. tried dvd on other devices and works perfectly.
thanks in advance

check the drive is running in dma mode and has not dropped back to pio mode

check your voltages and temperatures in the bios and post them

checked dma and its all set up correctly.

what does the bios list for the 12v line
sandra list it as close to out of specs

what are you running
video card
cpu
m/board
ram
power supply
brand
wattage

check the listings in the bios for voltages and temperatures and post them

slightly concerned about why you want to check voltages / temps etc
computer has been running for ages without issue, and cant see that there would be any hardware fault other than some issue with the drive itself.

i can return it to ebuyer, but i wanted to check all other options first.
regardless, if you could answer that, i will go get the temps/volts when i next log off.

8800gt
Pentium d820
nforce motherboard
570w psu, antec
1.5gb of kingston ram. in 1gb stick and 512mb stick
(i know ram isnt optimal, but sorting next week)

the 12v line is your main line,when it shows as low as that it needs confirming that is the correct reading
if it is the psu is a problem and needs replacing
but software readers are only a guide and are not always accurate

you could also try a new 80 wire ide cable on the drive,yours may just have a broken wire in it
they become brittle over time and removing the plug can be enough to break on of the wires

bios stated that it was 11.9 on the 12v line.

but i would be rather surprised if there were any powersupply issues as its from a reliable brand (antec) and is only 2 months old.

dai

can you see it listed correctly in the bios

theonionking

yep, cant see anything wrong in the bios.
all temps and voltages are acceptable.
have also replaced the line to no effect.

dai

do you have a link to your power supply
