this is why i use RecordNow to burn DVDs. it does *not* manipulate MD5s, info files, BUPs/IFOs, etc.

ever since around version 5.5. of Nero, i've read of it being problematic with burning DVDs... at first, it was what type of DVD compilation to use (UDF or DVD-Video...) so the burned DVD would play on a settop DVD player. now with the talk of Nero manipulating BUPs and/or IFOs on the DVD video disc, i'm not too surprised. i will say this, the video DVDs that i have burned with Nero 6.3 (i think that's the version i have) work fine on my settop players. but i still trust RecordNow for my data DVD archived discs and use it most of the time anyway, as it accepts the VIDEO_TS folder no matter what type of file is in there. (some authoring programs put in other files, such as layout a.k.a project/.LAY files, and Nero gives an error every time i try to burn a VIDEO_TS folder with said file types, which is just an annoyance to click "OK" to disregard the file every time.)

i think DVDDecrypter is god for burning. but like jraras, i never found an option for burning anything other than ISO files with DVDDecrypter. if they included that in an updated version, i'd probably dump RecordNow. the fewer programs i can get away with using, the better.
