Hi everybody, I've had a Pioneer DVR-420 HDD Recorder for about 7 months now, and had no problems at all until the last few days. What appears to be happening is the picture switches between 4:3 and 16:9 at random times when playing back on my Toshiba TV. Naturally, the Pioneer is connected with SCART and I've not had this happen before. As it tends to record terrestrial programmes in letterbox 4:3 I just expand the picture to fill the screen using the TV remote. But it has now started switching back and forth between 4:3 and widescreen all by itself during playback. Even more disturbingly, it did a similar thing on a DVD (X-Men 2) I was watching yesterday, where it kept switching between the regular Wide screen setting (letterboxed) and Cinema (which is what I had set the TV to). Up until that point I had put it down to poor signal quality on the original recording, but I don't believe this should happen at all on regular DVDs. At this point, I am blaming the recorder rather than the TV as I don't get this problem when watching regular TV (from the aerial), or from my NTL box, or from my PS2. The Pioneer is set to use 16:9, etc. and has been since I first set it up. I have not changed anything. Does anybody have any ideas?
