i was wondering if it was possible to perhaps make an internal 'mute' button for MP where when u click it it only mutes MP so that u can keep the tv running in the background without muting the whole computers sound. i havent been able to find this anywhere in MP. could someone please let me know if this ability already exists. its pretty important to me. also it would be able to keep the timeshift buffer while u mute the program for awhile and do other things which can be very helpful.
