Hey I'm not sure if you've seen this thread, but it discusses auto framerate aka refresh rate switching.
Code:

I'm not sure if it works on all TVs but mine seems to work. Only thing I notice sometimes is when coming back to the EPG, there is a pause and some flickering, and sometimes 1-2 seconds of black screen, before the EPG comes back up. Maybe I'm lucky.
You're sure your TV supports true 24p? (some do not). Also, make sure you have it set 24p/60p and don't include 50p (Unless that's what your region needs, in which case you would likely disable 60p instead of 50p). Also, by any chance... Do you have BOTH the video resolution and the graphic resolution set to 1080p? If so, change the graphic resolution one to 1280x720. This is only the EPG and not the video stream so no worries. Try that if you can.
Edit: There is a volume setting in the inner portal system settings , but it only seems to affect the volume in the "IPTV Channels" are in the inner portal. When you go into stalker portal, that setting is ignored it seems. Weird thing is, I just checked 2 servers and my volume seems to default to 100%. EDIT2: Tried on a third server and it defaults to 50% so I think it's configured on the server side from the provider.
Cheers
