Buffer Issues with MPEG2 cards and line in

[sparkletron]

I have multiple computers that all suffer from the same issue. If I setup mythtv to use a line in as a channel. XBMC will have buffer issues playing back the video. Though if I pause the video in XBMC and wait 5 seconds and let it play it will play perfectly. Each one of these PCs are a master backend with the XBMC client installed on the same computer. The 3 pcs I have replicated this issue on are:

-2 Pentium 4 HT 3 GHZ PCs, one with a AMD HD 3650, and the other with a Geforce 4 MX
-1 AMD Athlon x2, with a nvidia GT630 video card.

All other dvd quality mpeg2s play fine on these computers and mythtv will playback the video just fine. Only livetv in xbmc has this buffer issue. Also the importance of this is many people like myself setup directv via the line in. Then a script is used for the channel change. In this setup the buffering makes the setup unusable. Though recorded video plays back fine.

On a side note mythtv 0.25 or 0.26 have the exact same issue, no difference. (I also can not test DVB, no digital signals out in my area).

Would you mind posting this in the forums? http://forum.xbmc.org/forumdisplay.php?fid=170
Problem is, that I don't have such a setup and therefore cannot reproduce this.
