[mythtv-users] Problems in "Watchs TV"

I'm using a 1GHz celeron system - I had to tweak a lot to get things to
work, but I'm ALMOST 100% happy with the results:

I have a 1Ghz cpu with an el-cheapo WinTV capture card
Some el-cheapo GeForce2 MX video card

My settings:

3000 Kbits/sec 
Max Quality 1
Min Quality 10
Max interframe diff 5
Enabled both interlaced encoding options, this seems to reduce the CPU load.

Disable all de-interlacing, and other fancy features.
Enable jitter-reduction on playback

MP3 audio
32000 KHz sample rate
Quality 7

My CPU runs between 75-95% while watching LiveTV.  Picture quality is very
good...but not perfect.  I've tried setting the bit rate to 3500, which
provides excellent results, but I then get some of the stuttering you

Good luck!!

I have the same issues, although my system is a little less powerful.
I've been wondering if some of my settings are wrong.  For instance, I'm
using mpeg4 because rtjpeg doesn't come as an RPM and I didn't feel like
compiling.  It could also be DRI not working correctly in Xorg 6.8.

OS: Mandrake 10.1 Cooker with extra new stuff from Thac
Processor:  AMD Athlon 900
RAM:  448 MB (or something like that)
HD: 10 GB (I know...tiny...I will run it on an external when I get it
working right)
Video Card:  3dfx Voodoo 3 (DRI does NOT work with Xorg)
Capture Card: Brooktree BT878 (ATI TV Wonder, I think)
Sound:  SB Live! (EMU10k1)

I would love to hear any ideas.
