[mythtv-users] 0.20 Mac PPC frontend on G4 550

Hi,

I have an old PowerBook G4 550Mhz with Mac OS X 10.4 that I've been
using as a spare frontend to play back recorded DVB-T content (no
HDTV) from my Linux combined frontend/backend. The experience was
never trouble-free under 0.19, because of the missing video
acceleration on the Mac frontend. (I'm no expert on this, but I've
been told that the Mac frontend didn't use all available system
resources to decode the video, putting the burden completely on the
CPU.)

I'd hoped that would change a little bit with 0.20, but the opposite
happened: In 0.19 the video would occasionally stutter but it'd play.
In 0.20 any attempt to play video times out with a black screen. I
tried playing around with setiing for frame skipping to no avail.

I've been using the builds from thesniderpad.com for both 0.19 and
0.20; I'm using the same build on my main laptop, an iBook G4 with 1.3
Ghz without any problems, so suspect that 0.20 needs more CPU than
0.19 on Macs.

Does anyone else have MythTV 0.20 running on a G4 550 or a similar system?

Jens
