Just for the record, I experience this problem with revision 8905.

On a remote (over a WLAN connection) frontend machine that has 256MB
RAM and a Duron 800MHz CPU, I get around 30 sec channel change times,
and when I check the position bar after the channel is changed, I see
that I have 30 sec of the program "to go". The video seems to "speed
up" to catch the rest of the video for a while, thus jumping a bit due
to the little processing power of the frontend machine.

On the machine that hosts the backend (P4 2.6GHz, 1GB), I get the same
effect, only it's less drastic: the change time (and the prebuffer
length after channel
change) is around 15-20 secs.

The previous revision I used to run was 6946 and the delays was then
around 5-10secs which is (almost) tolerable.

Anything I can do to help tracking this out?
