Hello all,
I am having a problem with mythtv 0.18.1 on Gentoo kernel 2.6.12-r10 on
both livetv and playing pre-recorded videos.
The play back is supper choppy and pauses about every 2 seconds.
Playing the same file directly through mplayer or gmplayer and it runs
as smooth as butter.
The recording works fine though even while recompiling X in the background.
I am running on a somewhat slow system: P3 800, VT6x4 mother board, 512M
ram, Radeon 9250 256mb, PVR150, SBLive.
I am using the ATI binary drivers 8.16.20.
I also had the same problem with an Nvidia FX5200 card in the system,
but had to return the card because of less then desirable svideo output.
Thanks for any help!!
Lee
