Just a quick warning to anyone planning to use Nero for SVCDs. There's more info on vcdhelp.com but the gist is that Nero doesn't quite make SVCDs that fit the spec. On my Apex 600A (with the N6 firmware) I can't fast-forward any Nero-produced SVCDs. It rewinds instead, for some odd reason. Just playing the disc works, but FF and some menus don't.
If I take the same files and use VCDEasy to create the disc, it works fine. I can even rip the files from a Nero-produced disc and remaster the SVCD with VCDEasy, and it'll be fine.
VCDEasy also supports menu creation, although it's not entirely obvious. It took me some reading (links from vcdhelp.com) to figure out how to make it do what I wanted it to do. Once I figured it out, though, it's pretty straightforward. Now I can use BMPs or MPGs for menus, make submenus, etc. It's pretty cool. And best of all, VCDEasy is free. (For the record, I have a legal, legit copy of Nero 5.5, but now only use it for data and audio CDs, not VCDs/SVCDs.)
