[mythtv-users] Best way to Send Video via DVI

[Nathan A. Smith]

Hi,

I am trying to tweek my mythbox to get 2 problems solved....

1. HDTV (getting it via firewire) is sporadically jumpy.  At earlier
viewings it seemed fine, but now it is jumpy enough that it is BARELY
watchable.  During watching HDTV -- I am seeing CPU usage at 147% and
memory usage at 51%

2. While all the tv shows (both HD & SD) display pretty close to correct
-- I can't get any other screen to fill my Mitushbishi TV fully.  This
is partially the TV's fault, to see the problem see this pdf file (page
78).

Does anyone know how to over come that?

Known issue:
 - Everything is on the single drive (both database and /mnt/store) 
 - I haven't enabled XVMC as I figured I should have more than enough of
   a system to a handle this....

Thanks in advance.
