Daniel: >Do you suppose it could be also a problem with the Pioneer DVR DVD >drives. I have a DVR-109 and do havve the DVD playback problem. You may be on to something there. I have the DVR-105. I can't recall it all, but when this issue first surfaced, there were many reports on XLR8YOURMAC (www.xlr8yourmac.com), and it seems to me that there were "all-OK" reports by some w/DVR-109s too. It may also be a firmware revision thing (either DVD drive and/or Radeon card). My Radeon card is still at the original firmware rev. as delivered years ago, as is the DVR-105. Sean
