For DVD's I found that Ulead DVD Workshop works well for me in generating the movies, the chapter stops, slide shows, menus and custom look to the screens. It's burning function has been really reliable using a Pioneer A104 and A106 but be warned that while it is multiplexing it can take a whole day to generate the files and the disc image before burning. This process also needs about 25 Gb of free space for temp filing as it generates the files and finally the end files will take up roughly 3 times the original space as the original 4.4 Gb file you were trying to encode (leave some empty space so you don't find out after processing that you don't have enough space). Warning though, DVD workshop uses PCM audio which does not work on older players.
Nero 5.5.09 has also worked well for me in generating CD-r/rw's and DVD-r/rw. My A106 is a multi-format but I have no use for DVD+r so I can't say how well Nero works for that. Since I use DVD workshop, I have not tested Nero for video DVD's. The data DVD's have been readable on all of my computers.
IMHO Roxio easy CD-creator now sucks. It is a huge program, temperamental and has so many conflicts with other programs that it drove me nuts (one was even with Adobe Acrobat 5 which is a very common program). The video DVD's it created worked ok but I found it restrictive in the creative department for customizing your DVD project (and less intuitive).
Lastly, as a note to all about 321 Studios DVD-express (I should probably keep this hush hush) but the company lost it's suit with the US gov't antipiracy commission and was ordered over a month ago to stop distributing its DVD-express with the content security system decryptor keys (the stuff that digitally unlocks the disc contents). DVD-express is no longer available on the web with the keys. However, Future Shop had a couple of copies of DVD-X Copy Platinum which contains DVD-express with the decryptor key. If you want to "back up" DVD's this is the last of the software that easily "backs up" your encrypted content.
For those who don't know, DVD Xpress will basically "back up" the whole disc (menus, extra content and the movie) and only adds a screen that says the disc is a backup. Since real DVD's are multi-layer they hold 9.4 Gb of data. DVD Xpress will compress the data to fit a single layer DVD-R. There is a small loss in image quality and may be a small pause in the movie where the original might be switching layers, but not really that big a deal and certainly better than those awful VCD's and DVD clones from China.
DVD Xpress works well (only a few DVD's where the menus and extra content would not burn but never encountered a disc where the movie itself could not be backed up, but this was with a "free, patched" copy from Kazaa). Now that I have the licenced copy, no glitches yet.
If you plan to snake a copy from Kazaa, pls read my virus warning first.
