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.
