ive captured mini dv to my pc, then used TMPGEnc to change it to mpeg, ready for authoring to dvd.

ive played back the mpeg in windows media player and am fairly pleased with the result. all except the last 5 minutes. then the sound goes off, and the picture goes a bit 'blocky'.

can anyone suggest a reason for this please? i played back the avi file to check that was fine, and it is. so im losing something in the changeover.
