I usually use it to play DVDs, but this weekend I decided to get out my old VHS tapes. I popped in a Wizard of Oz VHS tape from 1999 and the picture is fuzzy and grainy. I adjust the tracking, and the picture improved but the sound went away. I tried several other VHS tapes but they had the same problem. If I adjust the picture I lose sound, if I adjust the sound I lose picture quality. My guess is that my VCR is decoding audio at the wrong frequency.
