[mythtv-users] Nehemiah Performance

[Tako Schotanus]

Ok! Got mythtv working with the hardware mpeg decoding!
Not finished yet but a great job so far Isaac!

Get as low as 20% and never higher than 30% when watching live tv using 
450000/600000 @ 464x576, this was consuming around 90% in software.

The image I get is corrupted though, it seems as if large rectangular 
blocks in the top right part of the screen are always off by a frame or so..

And if I press M to go into the EPG it won't show the thumbnail sized 
version of the current channel but more importantly the screen goed 
black if I leave the EPG. ESC and going back into LiveTV solves this.

Cheers,
-Tako
