My wife's Sony digital camera takes MPG videos. I have been unable to view them on my PC with Picasa and WMP for a while now and I want to figure out why. They will open in VLC perfectly. If I open them in QuickTime, the beginning is a bit choppy, like it's trying to load the file or buffer it or something, then after 5 seconds it catches up and plays. In Picasa, I get no video and the audio is garbled and makes a screeching noise.
But - it does work fine on her PC and also on mine with VLC, so it's not the file. I've downloaded codec checking programs and can't seem to make any headway with those. Maybe I'm not using them properly. Any ideas?
