I just put in a Sony AD-7190A burner into my 5045 today and it is working great so far. I first put it into my computer and upgraded the firmware to 1.05 (from 1.04). Then I put in a region 4 DVD to set the region code, but it played the film right away without asking for a region code.
I had some trouble fitting it into the DVR, but after an hour or two, I managed in the end. I still need to secure it better, though it’s sitting fairly snug in there.
I put in an old DVD+RW that I had lying around and burned a couple of video clips to disk, no problem. I played back the clips from the DVD+RW and they played fine and I could Fast Forward.
I then put in a region 2 PAL DVD and this also played fine. Fast Forwarding also worked.
