Hi there, after updating to 3.1 on my 2nd gen iPod Touch, I restored it and loaded some videos I converted. On playing those files, the video would play normally until at a random point the video frame would freeze, while the audio continues to play. If I quit the video app and go back to the video, it would play again normally for maybe 1 minute and then the video frame would freeze again, while audio still continues. These video files were working perfectly before I updated to 3.0, so I doubt that there is a problem with the files. Could someone suggest what I should do in this situation? Should I revert the firmware back to what it was before updating to 3.0? Thanks in advance for your help!
