If you do get a Mac, get Metadata HooteNanny

Don't know if there's a Windows equivalent.
I'm not sure how you'd get your MOV file into Pinnacle Studio. Here's some ideas (I don't have Pinnacle, so I can't test these).
You can use a combo of the Haali Media Splitter along with ffdshow-tryouts.

http://ffdshow-tryout.sourceforge.net/
For the latter, check the box VFW interface and VirtualDub plugin anyway during setup (not 100% sure if needed, but can be handy later). If you don't need anything, uncheck all the boxes when you get to the audio/video codecs to decode page. When you're done with installation, go to your start menu, ffdshow, video decoder configuration. For H.264 set it to libavcodec. Then go to your start menu again, ffdshow, VFW configuration. Go to the decoder tab and pick codecs. For H.264 also set it to libavcodec. If the Haali splitter is also installed, then reboot. Try playing your Canon MOV samples with Windows Media Player (they should work). Then try opening them in Pinnacle Studio (may or may not work).
If it doesn't work here's another possible route. Can Pinnacle read MP4 files with the H.264 codec? If so, you could try losslessly transcoding (losslessly copy the audio and video streams from one container to another) from MOV to MP4 using QuickTime Pro. Open your file in QT Pro. Click file, export. For the export box, pick export to MPEG-4. Click options. For file format pick MP4 (I tried a few Canon samples and apparently MP4 ISMA doesn't offer pass-through). For Video, under video format, pick pass-through.

Then same drop-down menu where video is at, pick audio. I tested on some samples and apparently audio has to be reencoded to AAC (I think the SX1 IS records in 16-bit Integer Little-Endian, 44.1KHz, Stereo). You'll have to play with the audio settings because I don't know much about audio (or maybe someone else can make recommendations). My only recommendation is you'll probably want to keep the same sample rate (in KHz) and number of channels (mono, stereo, or more). And under streaming you can leave it as disabled since you're not streaming it over the net.
