Summary: 4 weeks after ordering, my RD-XS54 will not play a DVD. I have a Toshiba DLP HDTV and other electronics that have been great. Just bad luck here that's an inconvenience. I still recommend the RD-XS54 unless you find a DVR with component inputs.
Pros: Many options for setting DVR (HDD) and DVD recording quality. HDMI 1080i is very clear. Good built-in editing. Network Navi is cool. TV Guide works well for me despite reviews to the contrary. You can DVR and watch what recorded prior or a DVD at the same time.
Cons: Best recording input is S-Video (component inputs would be better). Fan runs 24/7 even with HDD shutdown enabled. TV Guide screens are slow. Cannot get Network Navi email recording setup working.
