April 2007, PC Welt: Quotes and excerpts from the review:

"Tunebite records DRM-protected audio (and for awhile now even video) files while they are playing. The resulting recordings are free from copy-protection and can be used without limitation.
 
System drivers enable the playback and simultaneous recording at up to 4x speed. In our tests, the recording process worked without a hitch and without detectable degradation in audio quality.

With videos, however, CPU power quickly became a limiting factor. The software publisher recommends a minimum processor speed of 2 GHz for the conversion of videos. Our installation on a slightly slower system showed this recommendation to be prudent. Tunebite will only record in the MPEG4 format when the 3ivx codec is installed. The recording process will not function with the DivX codec.

For the conversion to MP3 format, an external encoder (LAME) is required. This is not delivered with the product. Tunebite populated the ID3 tags, lyrics and album cover artwork for our files even when this information was not present in the DRM-protected originals. Test version on CD. Bottom Line: Problem-free operation. A fast CPU is recommended.”
