Issues build Openelec Pulse r11101

Hello,
I'm using the openelec builds from pluse eight. In the newest version I have found 2 issues.

1. XBMC isn't using the channel numbers of the backend. I'm using tvheadend and on previous versions XBMC was using the numbers I set on tvheadend. But now this numbering is gone in XBMC. The option to use the backend numbers is still on.

2. Live TV is 25hz/50hz, and most movies are 24hz. So I set the display to switch to 24hz when a movie is played. That was working on the past build (builds before that had some sound delay issues). But when I turn the option on now, I get alot of frame drops. The movie is unwatchable. It looks like XBMC isn't using the hardware excelleration when I use this option??

My systems:
Acer revo 1600 (single core atom, ION1)
Zotac Z box (dual core atom, ION2)
Both have the same issues.
If needed I can post a logfile.
