I'm also using the latest SIS driver from winischhofer.net. Hmm, when I play the pchdtv.com sample in mplayer, I get video of some people on a train (and it's doubled horizontally so there are two images of the same thing).
Yeah, it's interlaced or some such it seems. The picture quality is quite bad over all.
When I play the same one within Myth, I get video of a man and a woman singing, and it plays completely properly.
I assume you're using the MythTV Internal player to do this? I've never seen this 'other channel' you refer to from within xine or mplayer. I also haven't bothered to try the MythTV Internal player either. to the best of knowledge there is only one channel in the stream but I'm not sure how I would check it from mplayer or xine.
You say you had to abandon onboard SIS. What did you use instead? My Pundit has no AGP slot.
Low end ATI 9200SE with DVI out and the Xorg 6.8.2 radeon driver. Playback is done with Xv. The xorg radeon driver has an Xv scaling bug where the right 1/4 side of the screen renders as a pink bar with 1920x1080 sources. I wouldn't recommend ATI cards because of this.
A small aside... The 1.0.1 version of xine-lib has a video option for the opengl driver called 2D_Tex_Fragprog that supposedly is as fast or faster than Xv on "modern graphics cards". On my Pundit with ATI 9200SE PCI glxgears gives me a whopping 450fps which frankly sucks (yes, glxinfo shows direct rendering enabled and xfree logs show glx and dri loading just fine) which makes the new xine opengl playback perform like crap with any size video stream. I figure the bad opengl performance is a result of the slow PCI bus on the Pundit. As for the onboard SIS in the Pundit there is no opengl or dri support so all this is pretty much irrelevant unless you plan to put in a fast PCI video card. What might be really interesting is to see the CPU performance of a modern ATI card using dri and the opengl output from xine-lib 1.0.1 when playing back HDTV streams.
Getting back to the Pundit... My old SIS config was back on MythTV 0.16 with Gentoo 2004.x. Back then I was using xorg 6.7.0 and sis_drv v200804. I did recently try the current sis_drv with xorg 6.8.2 on Gentoo 2005.0 and saw the same video jump/sync issue that caused me to abandon it in the first place. To bad really since I liked the onboard better than I liked the ATI 9200SE. No, I don't have any of the old config files any more.
