I need to record long continuous audio programes (over 90 mins) and remember using vhs nicam machines in the past. Can you do the same with DVD machines ? Do you need a video signal(could rustle us a test generator or old camcorder, but do I need the hassel? what do the various record qualitiy settings do to the audio? and finally, does anyone do a machine that will also record direct to CDR/CDRW? all pc dvd drives will do this, do any domestic dvd recorders? Thanks for the help! Mark.
