WoW!
I had an old VHS tape we wanted to look at. I hooked up an old Fisher 4-head stereo VHS ( left/right audio, composite video) to the Marantz SR8002 AVR, which is connected via HDMI to Vizo LCD TV.
The picture was actually pretty amazing, better than the original VHS I remember!
The upconvert works pretty well, from composite video to HDMI. My TV is only 1080i ( still need to upgrade to 1080p maybe next year).
