I've managed to record 48kHz Dolby Digital (from an XBox) sucessfully.
I used a Soundblaster Audigy 2 with an optical IO bracket I built, but would
guess that the versions with a live drive would work.
Instead of creative's standard driver, I used the kX project driver which
allows for direct recording. To actually record the data, I used Adobe
Audition, configured for 48kHz, 16bit Stereo.
The file was saved as a .pcm file (raw data), and was then truncated with a
hex editor so that it started on a frame. When renamed to *.ac3, PowerDVD
played it quite happily, and my amp recognised it as being Dolby Digital.
Hope this helps,
