I have two Magnavox/Funai H2160MW9 DVR/DVD recorders and the discs I have burned have playback problems on my Oppo 970HD DVD player and the two different optical drives in my PC. One recorder is the original version, the other is the newer 'A' version.
On the Oppo, the playback studders, but interestingly, if I pause or stop playback and resume, the studdering usually goes away. This happens on multiple discs, anywhere on the disc and at anytime. Sometimes the video plays correctly the first time, if not, I can usually 'fix' the problem by stopping and restarting playback. Sometimes it takes two or three tries to get it to work.
All of the material that was burned came off the HDD from S-VHS transfers. I also tried a time shift recording off of 'cable', but the problem is still there (at least during PC playback).
Per recommendations, the last media I have tried were T-Y and RiData 8x -R's. Previously, I was using TDK, but there is no improvement.
I understand these stand alone DVD recorders, unlike optical recorders in PCs' have record issues. This is my 1st stand alone DVD recorder. I have burned well over 150 DVDs' in a PC with little issues.
