I captured TV shot to AVI using iuVCR, codec PicVideo Mjpeg. The capture was done overnight, it should record two shows at different time. Recording time for first show 2.5Hrs and second show 1Hr. Break between recording 3 Hrs. When I checked my computer in the morning I had to login to WinXp ( however I disabled screensaver and specified not to shutdown disk), I could not open first show AVI but second was recorded correctly. Initially first avi size was 0, later it changed to 8 Gig, I tried to open this file with different players without success.
I reimage my harddrive and this did not help also.

Any ideas ?
