I have a Sony SLV-575UC VCR that's having playback issues. Whenever I play a tape, it starts out fine but then it starts to pause every few seconds for about half a second, then continues to play. It does the pause thing at intervals of about 8 seconds. Does anyone know what could be causing this and if it can be fixed? Do I have to take it to a VCR repair shop, or could I fix it myself? I'd like to get this VCR working again because it's a really nice machine, and I have a bunch of tapes I'd like to rip to DVD. Thanks for any advice you can give.
