I am running the 2.5.5 with the latest patches. When I am on Live TV and change the channel, Live TV completely freezes. Sometimes it comes back if I wait a few minutes and sometimes it does not. Also when I try to change the channel, I hear about a second of the new channel's audio before it freezes.
I have tried different decoders and changed the Live TV buffer directory without any luck.
I had this problem awhile ago but it went away with an NPVR update...
Current logs attached.
