Do you have DVB-EPG enabled?What i really want is to not have to reboot MP every time i want to record something. I wish the 'stop record' button worked. I wish launching a video worked every time without requiring a restart. Basically i would like to not have to restart MP 2-3 times per day for only a couple of hours of actual use. I really really really wish the development focus would be be on stabilization of the current version instead of themes and extensions.
I had a similar problem where if I left the pc for any length of time, or even tried changing channel after the initial channel load, tv server would lock up until I killed the process. Since I disabled DVB-EPG this problem is completely gone.
Hope this helps you.
