Well, I'm not sure if it's the right choice, too. This is why I
asked for test results. I have 3 CD-ROM-like devices, 2 of them
give perfect playback (a burner and a DVD drive), while one
older CDROM cannot handle the CDROMREADAUDIO ioctl at all. So
quality may depend on quality of your hardware. But I guess that
most never drivers will work.

The reason why I would prefer something like cdfs is, that it's
so simple to use. There would be no difference in playing a song
from harddisk (mp3 or other format) or playing cd-audio via cdfs.

Another point is, that tools like cdparanoia may be too slow on
the average VDR machine and they completely lack a remote
interface to control them for track jumps and seeking. From the
early days of the MP3 extention (when mpg123 was used for
decoding) I know that handling with an external tool is
complicate and error prone, too.
