well, I'd seen others report the same problem and many swear by installing the DivX Total Pack of codecs. Well, it didn't work.
So now I have both the work & home pc with the same software, same codecs (all the same versions) but still a sync problem, though it has improved.
I just noticed there is one other difference for the work PC - it has no audio device, i.e. sound card.
CBF, I'm waving the white flag on this one...
UPDATE : you knew there would be one, right?
Ok, I downloaded DMF 4.0. When I ran it, the thing just closed with a critical error.
hmmm.
I installed another codec hoping to get Nero to work, but instead, it got DMF working, go figure. I can tell DMF uses this codec, because it fires up an icon in the systray - the codec is ffdshow.
Nero doesn't use this codec because the icon does not appear.
This codec seems to fix the problem, I've watched a burnt DVD all the way through, no problems.
The question is, how can I force nero to use this codec?
