I've recently upgraded my projector to a Mitsubishi HC6500 (1080p). I have recently learned of an interesting problem. I have a DV-983h connected via HDMI cable (Blue Jeans BJC Series-1) through a Yamaha RX-Z11 receiver. Interesting thing to note is that if DV-983h upscales the video to 1080p with the Yamaha Z11 set to "pass through" the HDMI input signal, then no video signal, at all, is output from the Z11 and audio become "choppy". If I bypss the RX-Z11 and connect 983h directly to the HC6500 with the 983h providing the video upscale to 1080p, then the projector correctly displays a 1080p image. If I set the 983h to output video at 480p and subsequently set the RX-Z11 to perform the video scaling to 1080p, then the projector displays a very nice 1080p image.
I believe this is an issue within the Oppo DV-983h. Communicating with Oppo about this I have learned they are already aware of this issue. Oppo claims they can neither test nor correct the problem as they do not have an RX-Z11 to test with. I have found several references to this problem on the internet in other websites. Some folks suspect it may be a compatibility issue since both the 983h and the Z11 use the same Anchor Bay video chip may be causing a conflict. I would suspect that the other Yamaha receivers using the same chip may exhibit the same problem.
To date Oppo has not responded with how they will approach correcting this issue for me, and other users with same problem. I had been plannig to acquire the Oppo BD-S83 Blu-ray when it became available, but with Oppo's poor response to correct the 983h issue fo me, I am rethinking my purchase of the BD-S83. I fear that since Oppo cannot identify nor correct this porblem in the 983h, then the same problem may carry over to the BD-S83 as it also uses the Anchor Bay chips. Interesting to note, I had offered to Oppo to participate in their BD-S83 Beta testing long before they "randomly selected" their Beta testers, but Oppo declined stating they already had enough testors. I find it curious that Oppo is reluctant to risk identification of a continued potential problem with a new Beta unit which they are preparing to distribute soon.
I really liked the Oppo DV-983h when I first installed it in Oct., 2008. That installation included a 720p projector. The displays had been impressive, especially considering the price range of the DVD player. Upscaling to 720p was not an issue regardless of the various combinations I tested. However, now that I can project a 1080p image, I am concerned that I may not be getting all of the video/sound "quality" available from the source material via HDMI. I currently have the DVD player set to output a 480p image and allow the Z11 to provide the upscaling. I have read that setting the DVD player to 480p may also inhibit sound production as this setting may limit the bandwidth available for audio through the HDMI connection.
I realize the DV-983h has now been discontinued, but I wanted to post my observation about this unit. It is a real disappointment to me. It appears the DV-983h was not the perfect unit everyone believed. Snce they have discontinued the player, my fear now is that this problem will never be addressed by Oppo. My concern is they may not correct any similar problem in the BD-S83 should it appear.
If anyone else has noted this problem and possibly devised a resolution please pass it along. I have tried all possible setting combinations on the various pieces of equipment to no avail.
