I've had this problem with CVS before 0.17 was released and still have
it in 0.17-release and recent CVS. I can view 1080i LiveTV, but not
after viewing any other resolution. So if a 1080i station is the
starting channel when LiveTV opens then I can view it, but if I am
viewing a station that is 720p and then change to the 1080i channel
then mythfrontend does a Segmentation Fault.
Hardware is a ASUS Pundit with a 3.06Ghz HT P4 and 256MB of RAM (64
dedicated to on-board video). I'm using the s-video out of the
on-board video. Tuner card is a HD-3000 and I'm using the DVB drivers.
As additional notes, I have to use lib2mpeg decoding otherwise
mythfrontend segfaults whenever I try to view 1080i. And with lib2mpeg
1080i still stutters even with de-interlacing off, but I'll try to
resolve that later.
Any help is much appreciated!
