VCR problem

[andy]

Try recording on the tape in another VCR to see if it did really erase the tape, or if it's actually damaged. If it erased part of it, then there's probably some magnetized oxide on one of the tape guides. I've seen this before and it usually causes a white line to appear on the recording. If it's damaged, then you should look for what's causing the damage. Bottom edge damage will cause an unstable picture since that's where the control track is. Usually a bad, or dirty pinch roller causes this. A bent pinch roller arm will also cause edge of tape damage (it doesn't take much to bend it).
