I am using Clear QAM cable and have a problem with some program channels. These channels are shown in the TS stream as "Stream Type: 0x80 DC-II Video" (See Program 2 below) These channels are not encrypted. TVServer fails with "video was found, but audio was not found after 15 seconds" error message (see log excerpt below). VLC and my Sony DVR have no problem with these program channels, only an issue with MP. Looking at the MP code it looks to me that the issue is that the video stream type 0x80 is not supported and therefore the error message (although the message is misleading .. not actually an audio problem, but a video problem).
Has anyone looked at supporting the 0x80 DC-II Video stream type? As far as I can tell it should be supported the same way 0x02 MPEG-2 Video is supported as it is basically an MPEG-2 standard 4:2:0 stream with a long delay between I frames. Just as a quick test I was going to change some code to define the video 0x80 stream type identically to the 0x02 MPEG-2 Video, but so far I haven't been able to get MP to compile before making any modifications so no point in making any changes yet;-)

I think my compile problem is because I tried to use VC C++ 2008 Express. I'll work on those problems. Meanwhile, is anyone interested in trying to define 0x80 exactly as 0x02 as a quick trial or does anyone see a problem with this approach?

Program 2 does not tune. Program 12 does tune.
