Got a Pioneer 525 that starts to breakup when into hour 3 of a DVD looks like a heat problem but not sure. Watching Lord of the Rings R1 and other long DVD it start to corrupt sound an vision around chapter 33 onwards. Stop and turn off for a while and its fine. It has a Techtronics mod. Was hoping to keep it going for a while till I can save my penny to buy a prog scan PAL/NTSC model in the new year. Any ideas on a fix or whatever?
