Hi guys,
Not sure if this has been asked before.  But I want to partially upgrade my home theater system.
I want to replace my TV and DVD player with a new LED HDTV of some sort but limited to 32" unfortunately by my nice solid wooden cabinet which I don't want to replace and noone seems to make 36/37" models anymore and a 40" is slightly too wide. And a new DVD/BR player.
I don't see much point replacing my perfectly good Sherwood 6.1 channel amp and would still like to use this to power the audio side of things. Only issue is the highest level video input on the amp is Y/Pb/Cr which is how it is currently connected to everything. Obviously to get the best picture I would want to change the new DVD player and satellite TV to use the TVs HDMI inputs, but what to do with the audio?
Is it likely that I can run a digital coax out from TV to amp and get 5.1 digital from whatever input source the TV is on? Or am I better off to run a seperate coax cable from each signal source to a separate amp input channel and have to select the desired source on TV and AMP?
I realize I  should just buy a new amp, but this one wasn't cheap at the time, and it still does an excellent job of powering my Wharfedales, so seems a waste just to get HDMI ports so I can be lazy and only have to change input channel on one device.

Any pointers are appreciated, obviously I got into home theater just before the HDMI bandwagon so am a little out of the loop :)

If you receiver has digital Audio inputs, I would run separate cables to both the TV and receiver - I do not know if the TV would pass 5.1 back down to the receiver from its digital audio output.

This means you will need to change two sources when you change your viewing source (TV and Amp), but a Logitech Harmony remote would make that a lot nicer.

Thanks for that, I did read elsewhere that a lot of TVs actually only output 2ch stereo on the digital out so no good as an audio passthru.
Thats good then so all I will really need to buy extra is a DVD-TV HDMI cable, already have one that came with the freeview receiver and already have digital audio connected to both sources anyway.
Have to test and make sure amp will accept Coax audio without a valid video connection on that channel since the digital channels can only be tied to a video channel. Should be fine, I just remember having a TV that wouldn't display a picture unless the audio cable where connected to something even if there was no signal on them
