It could be the recording mode problem.
If you record in Video Recording (VR) mode, the compatibility is less than video mode.
I think the way to check is if you happen to record program with Nicam and the NIcam still works on your DVD-RW on your DVD recoder, then it's likely VR mode.
Why VR mode? It's my understanding that this mode offers flexibility in editing, building the menu, do the chapter while the more widely compatible Video mode offers less. You need to choose which mode you want before you make a copy krub
Trade off krub between editing power and compatibility.
