I couldn't get any help in the main so I figured this was my next best bet. It's a Sony DCR-TRV460, digital 8. It's a few years old but I've never had any problem with it until recently. Everything works like it should, except for the playback. Whenever the camera isn't stationary the playback is really choppy with lines going across the screen. I've taken it to a few places to get them to take a look at it and the cheapest one was $250, and the guy said what it might need it just a thorough cleaning so I didn't leave it. Any ideas what's wrong with it?
