Question

I recently bought a new DVD/VCR machine. The VCR is the problem, tapes are jumpy, many lines across the screen and close captions are distorted. EVen just watching TV without tape or DVD, close captions are distorted. This machine doesn't have auto tracker and I can't seem to track it myself.
