Thank you for intelligible replies. The main reason for why window 
manager is unwanted is additional efforts in choosing it and tuning. 
I think, everyone who first got acknowledged with MythTV gets into 
topic of what window manager is lighter and how to proper start and 
tune it. It have taken time for me and will so for everyone. Apart 
from that any additional component is a stability loss. Each program 
may have memory and cpu leaks and be the source of system quirks.
