I'm probably posting this in the wrong section. Accept my appology if I have. Anyway when recording in LP or SLP mode for about 6 or 7 minutes my VCR starts making a high pitch sorta buzzing noise. I've tried cleaning it with a dry cleaning casette but it still makes the noise. Please help me and dont feel cautious about breaking it to me if it's bad news. Thanks. P.S. This started when I used a new brand of tapes to record with.
