I compile my DVD's with DVDMaestro, but opt to burn them with RecordNow (the regular version). After doing tests involving Nero and RecordNow, I find that when I choose Data disk with RecordNow and simply put the AUDIO_TS and VIDEO_TS folder in just like a regular data disc, I find that both of my dvd players read the disc so much faster and EVERYONE I HAVE BURNED HAS WORKED 100% PERFECT WITH NO DATA LOSS. In addition, because I burn them with the data option I can easily directly copy the discs. I am just wondering if the discs I am burning are UDF 1.02 or UDF 1.05. Does anyone know or think they do? Thanks a lot.
