I have a new Insignia DVD-VCR Combo Recorder - Model IS-DVD100121 and it works fine EXCEPT for one very problematic thing: Whenever I play a VHS tape on the VCR side of this thing, there is this loud static on the audio channel that does not go away. Play a tape, and this crackling buzzing can be clearly heard throughout playback. I have two other VCR's and play the same exact tapes on those machines just fine. Anyone ever had this? Any suggestions on how to correct? Thanks much
