K3B is the CDRW mastering and burning king: Data CD's, fullspec audio CD's, mixed mode, exact/secure audio ripper, VCD 1.1, 2.0, SVCD, CD-i support (Version 4), DVD Ripping and DivX/XviD encoding, ISO and cue/bin burning, initialization of IDE burners without the old tricky IDE2SCSI alchemistic invention... exhellent stuff.
Compiling it is quite tricky, as it uses a lot of gtk and qt resources, but it's almost sure you will find a pre-compiled one for your distro at rpmseek.com
It also comes now as default burner app at both SuSE and Mandrake.
Only thing it misses is DVD burning, as the current status of cdrecord-pro dvd is rather tricky... You have to wait for that, or use cdrecord-pro dvd via console. The alternative is using commercial software (Gear pro Unix v. 4.11) which goes for $ 799 and is a huge piece of crap.
