[QUOTE="cheer, post: 776391, member: 89792"] OK, this one has me ready to pull my hair out. I have a certain subset of files that, when played in MediaPortal, give me no video. I do get audio. It is some (but not all) of the DVD rips that I've made personally from my own collection. All files are in MKV containers, with H.264 video, AC-3 audio, and .srt subtitles. I have some files in exactly that format that play fine, however. Now here's what's really weird: [list][*]It happens on more than one machine. It was happening on my current HTPC, and after 10 minutes I figured it was a stupid codec problem and walked away, as I was planning to replace it with a better machine anyway. But I just built the new machine fresh and it's doing the same thing. [*]It does NOT happen in WMP (i.e. WMP plays the files fine). It also does NOT happen in MPC (and yes I've disabled MPC's internal splitters and filters). [*]When I first built the machine, all I installed for codecs was PowerDVD, Quicktime, ffdshow, the Matroska splitter, and the Quicklooks filter for Quicktime. When I played the file in either WMP or MPC, I got the taskbar icons I expected to see (Matroska, FF-V, FF-A). [*]I uninstalled PowerDVD, ffdshow, the Matroska splitter, and Quicklooks. Then I installed SAF6. No change. [*]It doesn't matter which H.264 codec I set MediaPortal to; I still get no video on those select files. [*]If I change to VMR9 (from EVR), the videos DO play. But then if I stop the video, I get all sorts of artifacting in MP (and I presume that's because VMR9 isn't compatible with Win7). [/list] I'm attaching my MediaPortal log and my evr.log from when I tried to play the file. I also opened one of the files in graphstudio and am attaching a screenshot. If anyone has any ideas of where I should look, I'd be grateful. And if it's a problem in the files themselves, I can always re-rip them, but I'd sure like to know WHAT the problem is.
