I now have a Pioneer DVR-420H which is connected between an NTL set-top-box (a brand-new Samsung branded one) and a 2-year-old JVC television. The connections to both are RGB via SCART. When the Pioneer is in standby, it passes through the RGB from the NTL box to the TV and all is well. However, when the Pioneer is "on" (even when it isn't recording) there appears to be a problem with horizontal stability. The sympoms are as follows: every few minutes, the whole picture creeps to the right by a small amount (about 5% of its width) over a couple of seconds, then jerks back to the correct position. Recordings also have this problem, which I have stepped through one frame at a time to verify the above description. Has anyone else seen/fixed this problem with any AV equipment (not just the DVR-420H)?
