Guys

I am doing an install friday and we are hooking up the HR20 to a Pioneer Elite 1540 61" plasma using HDMI..

For Audio , We are installing a Theta Casablanca III Surround processor and I want to run a Tos Cable from the HR20 to the Theta piece for Audio..

I want to make sure that when the HDMI cable is connected to the HR20 that it still outputs Digital Audio over TOS/Fiber..

Please advise and Thanks in advance

It does. My tv has only DVI slots. I have the HDMI run out of the HR20 and a HDMI to DVI converter to plug it in to my tv. I also have the toslink audio cable running from the HR20 to my audio receiver. Works like a charm.

All outputs are live at the same time on the HR20. I run HDMI to my TV and a separate optical cable to my audio receiver; I get sound from both simultaineously.

Awesome, Thanks guys -

Are the Component video outs up or down when hdmi is on ?

I know most of the cable boxes here in NJ , When HDMI is connected they shut down the Comp. OUts.. Totally sucks for us high tech installers :)

Just don't try to listen with both active (volume up), as the phase difference between them is something to behold. No wonder there are lip sync issues! (nothing to do with the HR20 in this particular case...it happened with every receiver/hd receiver I have ever owned. That's why they sell audio delay processors and why some HT receivers have built in variable delay)

I have noticed with my particular setup that there is less phase difference (lip sync) with HDMI than optical...but I'm NOT going to listen to TV speakers. As previously noted, lip sync is HIGHLY variable. It changes within channels, it changes across channels (some much worse than others...ESPN-HD is very bad much of the time, but not all the time), it changes HD to SD (don't see much of it on MSNBC or CNN).

Lip sync is all over the map, some due to the HR20 (as evidenced by doing trick play things and being able to make it better or worse) and some is source dependent (both D* , network, and our own local HT equipment).

I really think the only "true" solution is going to be adding a delay processor (and it will need considerable adjustment in response to the varying delay environments noted above). I think one of the popular devices is the "Felston" or some such...I just can't keep it in the ol' ******, because I'm in no hurry to buy one.

I cringe every time I see questions and comments about lip sync...because the nature of it is so complex...rarely do the "answers" consider all the variables that are impacting the problem, and none of the solutions work for all situations (except an external delay processor).
