Improve noise rejection?

Hi,
I had posted a note sometime back regarding getting ripple like interference on my TV while my VCR is hooked to my TV and home stereo system. I have swapped different components and tried different things since I posted to find the root cause of the problem and it is the VCR which is the culprit. My VCR is a 2.5 year old Toshiba M784 which I find to have excellent picture despite this noise issue. When I unplug the VCR from the chain, the problem goes away. And the noise is sometimes more sometimes less. I have tried ground loop isolators, better power strips, plugging things directly to the wall, but the only thing that makes any diffference is taking the VCR away from the loop. I think it has poor RFI rejection, because when the VCR input channel is on and blue screen on TV, I see the ripples and lot of rapid flickering on the screen. So I replaced the VCR with a couple different models amongst which was a $300 JVC S7900 S-VHS with all bells and whistles. The problem went away, but all the replacement units have noticeably poorer picture than the Toshiba both in tuner and playback mode. The difference is really noticeable. Question is
1) Can I somehow keep the TOshiba in the loop and avoid the noise?
2) If I want to replace the Toshiba, is there any unit that has comparable performance minus the noise? The current Toshiba units look very crappy to me (only 4 instead of 6 heads and no noise reduction technology, etc).
Please advise.
