<p>Synchronising audio between mutliple playback is notoriously difficult. If you can hear playback of one room in the other this will drive you nuts.</p>
<p>Jrmediacenter has a time delay funtion so you can tune this where al the sound cards are in one pc and even then its not brilliant and fiddly to setup. The only way I have managed it is to use one sound card which has both optical and coax digital outputs and run them into amps.... or use one amp that can power 4 speakers with two volume knobs...</p>
<p>Myth doesn't have a way to sync tv output between multiple frontends although people have played with various hacks and discussed it on this list.. using multicast and similar... but you get processing delay and all my comments about audio sync obviously hold true.<br>

I'm currently running a 0.23 system on Debian Lenny (will upgrade when 0.24 packages become available) using separate front and backend servers. My Frontend netboots from the backend with a NFS root filesystem and is connected via HDMI to my lcd TV in the lounge for video and a spdif cable to my amp for audio.<br>
<br>
I would like to add a slave system in the kitchen, so that we can watch TV whilst cooking etc, I'm currently investigating my options - The key requirement is that playback should be synchronised with the existing front end!<br>
<br>
This is what I've come up with so far<br>
1. New frontend system<br>
Pros<br>
Simpler cabling (cat already in place)<br>
Would be useful to have electronic cookery books/recipes<br>
Cons<br>
Additional computer required<br>
Unsure if synchronisation is posible<br>
<br>
2. Use a HDMI splitter to split the video signal to the second TV<br>
Pros<br>
Doesn't require an additional computer<br>
Cons<br>
Cabling will be harder although not impossible<br>
Audio will be an issue - need to supply down mixed audio not sure how<br>
Second tv will have a different native resolution (are small tv's/monitors available that will take a 1920x1080 input)<br>
<br>
3. Use second video output from existing front end's video card<br>
Pros<br>
Doesn't require an additional computer<br>
Cons<br>
Is it possible to output the same video in two different resolutions simultaneously?<br>
Audio will be an issue - need to supply down mixed audio not sure how<br>
<br>
<br>
Has anyone done anything similar? Any comments? Have I missed a better solution?<br>
<br>
Thanks<br>
