After a few days of media trial and error, here are some DVD media notes that maybe someone else can consider and save some video editing and burning time. The final DVD project was grainy so I suppose other factors are to be considered but this is when you see how the DVD media is going to treat you with a video deadline. Several methods were used to burn the DVD but I ended up using Pinnacle to Verbatim media and had no failures at all.
Project: 106 minutes compiled with Pinnacle 8. Usually exceptional quality but this one was a bit MPEG grainy.
DVD Player: One unit with Progressive scan and one without.
DVD Brand and Quality Note
Memorex (4x purchased two months ago - unavailable now) - 100% Reliable, never pauses. The best you can get.
Memorex (8x - the only Memorex -R available) - 4 out of 5 would not play at all on either progressive scan or non-PS.
Sony - Pauses during play on non-PS.
Fuji - Pauses during play on non-PS.
Great Quality - No quality. Always pauses and even with simple data backups will read slow.
Platinum - Least expensive and 95% reliable.
Verbatim - Least expensive and 100% reliable.
Time is money when we use bad media for training videos or other small DVD based projects.
Your mileage may vary.
