I 've burnt 4 copies of a 80 minute wedding video. I've watched one burnt copy all the way through... no probs.
I've visual fast forwarded through the other 4 copies and they seem to be ok, but I'm not really wanting to sit through the same wedding 3 more times, just to check the discs.
However, I noticed on one disc, when I stopped and played at the normal speed, a small green square appeared on the screen, and the disc stuttered a bit.... is this because it's not rendered properly, or the poor choice of media (Sigma DVD-R) I've choosen? :
BTW, the burner is using the latest firmware...
