Mythstream
Mythstream allows you to stream your recordings (and if you can get it to work) and live tv a-la slingbox replacement. I am having my own problems just getting it to play my recordings for more than 3-4 seconds at a time unfortunately. For some reason it will play the stream just fine for about 3 seconds and then just freezes. If I pause video lan and play again it plays for another 3 seconds. I am looking for a solution but until I find one I may just be stuck watching my recordings at home 
One thing I did notice was that the controls for mythstream didn’t work with knoppmyth. I found a quick post by craigtv in the forums that gets those controls working. Here is what he said that got my controls working.
Edit the following files ….
/usr/share/mythtv/mythweb/modules/streamtv/tmpl/default/selectstream.php
/usr/share/mythtv/mythweb/modules/streamtv/tmpl/default/createfile.phpin both files, find occurrences of this path …
/usr/share/mythstreamtv/
and replace it with …
/myth/streamtv/
You’ll need to do the same thing to the same named files in the …/compact directory as well if you use that template.
In addition, I found the path to the ivtv-tune binary in this file …
/myth/streamtv/ivtv-tune.sh
needs to be changed from…
/usr/bin/ivtv-tune
to…
/usr/local/bin/ivtv-tune
That makes the channel change command go thru, but I haven’t yet figured out what it’s supposed to do. I’d love to hear if anyone gets Live TV streaming, as it looks like that’s what it’s for.
That is all for now. I hope you enjoy.
