I've previously used Nero Express (from Nero 6) to rip CDs in many different formats, including Flac. Had to switch to Nero 9 to run under Windows 7, and there's only a few output options (wave,mp3,mp4). I've added DLL's which worked in Nero 6 to the plugin folders, but the output options dont change. Any suggestions? Are there different DLL's that would work?

I would scrap Nero and use Exact Audio Copy. It can do wav, flac, mp3, etc. It can also compare checksums to a database to be sure that your CD was extracted correctly.

I've never used it, but many people like Media Monkey...
