Is there anyway to trouble shoot a dvd without physically burning a disc to see if it works or not? I shot a wedding not long ago and have been having a really hard time making a DL DVD that plays consistently if at all on actual DVD players. Especially after going through maybe 7 discs before discovering maybe the fact that it worked on the macbook pro doesn't mean it will play back in the Panasonic Blu-ray player I own let alone the Playstation 2 or Sony Combo DVD player. After some investigation I discovered that my main menu had a duration of 40s and that seemed to make it work but that just seems weird to me I don't get this whole DVD authoring business anymore. On a side note I will never ever attempt to burn a DL DVD on my internal drive I had a 50% fail rate even on the Vertbatim discs everyone seems to recommend as the best out there, Memorex had a 100% fail rate and when I got to Imation I gave up and grabbed my 8 year old LiteOn drive out from under my bed which is lodged in a USB enclosure which I haven't used in at least 3 years because It doesn't always open when you hit the eject button and that actually managed to finish burning discs.
