I just recently picked up the Panasonic DMR-E50 DVD recorder and recorded my first disc, then finalized the disc. I then watched it in the Panasonic to make sure it worked, which it played fine in the recorder. My question is, when I put the DVD-R in my Pioneer DVL-909, it wouldn't play the disc. I also tried it in my Sony DVP-NS700P DVD player and it wouldn't play. Am I doing something wrong? Or will these players not play DVD-R's. I am trying to put all of my VHS tapes on DVD, but if I can only watch them on the Panasonic, is it worth having it at all? I mean if something was to happen to the unit, then all of the dvds that I have recorded are pretty much useless. I wanted to touch base with you guys to make sure I was doing everything right before possibly returning the unit to Wal-Mart.
