Today having ordered a new receiver, Onkyo 805 to use along with my RS1 and VP50 I would appreciate feedback on the best choice for "chain of command" wiring for best results and control using all HDMI connections.
Currently feeding BluRay , HD-DVD, and HD Directv via HDMI to the VP50 first for video and using toslink/coaxial digital sound switched by the VP50 to my older Denon receiver with best results of older audio formats. Now that I will be able to use the higher resolution audio of Blu & HD-DVD I would like to know most effecient audio/video connection path.
I will not be using the "video up-scaling" features of the Onkyo due to the VP50 in the path with calibrated inputs for all current video sources as mentioned above. I am concerned with the ability to control the audio without lipsync or delay issues and I am not sure if the VP 50 should be before or after the Onkyo receiver.:confused:
Your help in this matter will be greatly appreciated and hopefully speed up the install/swap of this 50lb beast when arrives.
Thanks
Glenn

Wow, I guess if I had asked for stock market or presidential election advice more would have answered, I guess I will just .....wing it!:rolleyes:

I have my VP50 before my Pioneer Elite VSX01. My DVD player and my DirecTV box run through the VP50 before going to the receiver (which I use as a pre/pro for my Emotiva amplifier). My PS3 bypasses the VP50 since I don't do any processing on the signal and goes directly to my receiver.
For DVD's, I use the multi-channel analog out on my Elite 79AVi if the soundtrack is 5.1 channels, as the DAC's in the 79 are better than my VSX01. If the sountrack is 6.1, I use the audio from HDMI. Here's the thing; if I'm running audio via analog, the VP50 doesn't adjust for any lip-sync (as analog goes directly to the receiver) but I only have noticed it out of sync when I do framerate conversion (this can be adjusted on my VSX01 by adding audio delay but is a minor annoyance). Normal processing does not delay the video enough to be noticeable. Of course when sending audio via HDMI, there is no delay since the VP50 compensates for it.
Another thing to consider is the number of HDMI connections your receiver has. Mine has 3, but he VP50 has 4. So basically, the VP50 is a better HDMI switch than my receiver in the aspect that it has more HDMI inputs. That lets me keep 2 HDMI ports on my receiver for components that need 1.3 compliant HDMI ports (allows HD audio codecs). I also found I can run my PS3 through the VP50 since it will only output HD audio as PCM, and I think you only need HDMI 1.1 for PCM (and the VP50 is 1.1, right?).
Sorry if there is no definitive answer in this, but I have my VP50 BEFORE my receiver if that helps.

My current config for BLU-RAY/HD-DVD (HDMI) 1080/24p and bitstreaming HD codecs going to Onkyo "set to pass through" then VP50pro then projector. I think most are running this way with good results especialy when bitstreaming HD codecs....
Hope this helps..

I think the VP50 will not pass the HD codes so your best bet is to feed to the 805 first.

That is the huge difference between the VP50 and VP50pro in this situation, passthrough for HD codecs. One of the reasons my VP50 is before my receiver and Blu-ray bypasses the VP50 and goes straight to my receiver.
I have two questions for those of you running a video processor AFTER your receiver.
1.) How do you deal with audio sync issues? If the audio is being taken before the video processing, are you just using audio delay in the receiver to compensate for any video processing delay? Isn't it easier just to let the video processor handle it?
2.) Are you having the video processor perform any processing on 1080p Blu-ray sources? The only benefit I can see is maybe if your player doesn't output 1080p24 and you use the video processor to convert the framerate from 60 to 24 fps (dependent on a display that supports 24 Hz of course).

Thanks to everyone who has helped with input so far. I too would appreciate answers to the above as I use the VP50 for my 2.35 constant height screen, can't really eliminate video processing for my setup to perform the appropriate stretch.
Thanks Glenn

Hi, first the main reason that I run this config is because I run Custom Resolutions for HD/SD and the Onkyo Reciever's will not Pass them...Second is because The VP50pro has A bug when passing the Bitstream HD codecs....
To the first Question 1, I dont have A audio Sync issue with HDMI in my setup....
Question 2, Yes, I have A BD 30 outputing 1080p24 YcBcR 4:2:2 + bitstreaming HD codecs into Onkyo set to pass through, into VP50pro then set to output A custom 1920x800p @48hz YcBcR 4:2:2 REZ to my CRT projector....
