If you mean burn music onto a CD from a video then its quite straight forward. Just feed the videos audio into the pc (analogue L & R will do it from VHS) into a recording package (or even Moviemaker on XP - I`ve done this off of VHS with great results) and save this as a WMA, then use a burning program like Nero to burn the WMA(s) to CD (remember to burn as audio, not MP3, and to finalise the CD)
Just keep the quality set as high as possible all the way and it works fine.
