My HDVR2 has been acting up lately. Tuner 2 kept popping up the signal loss message. When I look at the signal meter it showed both tuners with the same strength. So I switched cables anyway and same problem. I then took out the drive and ran it using SpinRite on level 4 (where it reads and writes to each sector) and it had no problems. So I put the drive back in and now on both the composite and svideo connection there is kinda wavy line through the picture and there are some lines through the picture and it looks a little dark. Does anyone know what could be the problem?
