I recentlt burned a DVD with nero that came out very blocky / poor picture during motion events in the movie. The DVD was a project compilation of several documentaries on a one 4Gig DVD set on super long play time. I originally thought it was the super long play setting but determined that this wasn't it because I checked another compilation I burned at same super long setting and it looked fine. I tried re-encoding the DVD files and this seemed to only make it worse. I determined it is not the DVD media or drive because the picture is very blocky even when viewed using PowerDVD on the computer. The only thing I can think of that I did different was that I encoded the compilation to my Hard drive first this time before buring to my DVD because using the on-the-fly encode/burn of nero seem to always crash lately, and give me coasters. Does it matter if I am using the computer for other things while it ginds away doing the original encode? I forgot to mention that the movies I am compiling into one DVD are avi files. THanks for any suggestions.
