You can only watch channels on the same transponder with one tv tuner. As long as your tvserver is able to tune a channel, afaik (haven't tried yet to be honest) it should be possible to start multiple streams (as long as your cpu can handle it).
I know... my question would be more specific if I was to phrase it as follows: Would I need second TV tuner so that I can watch whichever channel I wish in both of my clients?
Also is there a chance of supporting the streaming of multiple transponders?
Thanks.
