I had the 20GB mkv before and it played fine, but the AVCHDs are encoded in some peculiar way such that they’re impossible to remux into a matroska container and play successfully. High cpu usage and long delays are common on the players I’ve tried, that’s if it even plays at all. The m2ts files will play on MPC if I have HW acceleration enabled so I have to leave them in that format.

Did you try demuxing first?

Yes. When I demux the h264 stream before remuxing, the movie does start when it’s double-clicked but it still takes a while to catch up when you click in the seek bar. I notice when muxing im mkvmergeGUI that it takes a long time for the progress bar to show anything, like it’s reading through the entire file, then it shoots up to a hundred percent and takes another minute as it seems to write the file. I do lots of video converting/muxing and this is definitely unusual behaviour. I analyzed it in avinaptic and it showed a lot of buffer overflows:

It’s trying to play it with the DivX (MPEG4-ASP) directshow codec and not H.264 (MPEG4-AVC). MPC-HC has its own codecs. You don’t need CCCP, ffdshow or anything like that to play it back, use the internal codecs:

If that doesn’t work try VLC which only uses its own codecs.

No it isn’t. The divx reference is a quirk with avinaptic. I’ve tried internal and external avc filters in MPC as well as VLC and every other player but no go. VLC doesn’t show a picture at all.

I’m finding it impossible to remux the v2.5 AVCHD into a functional mkv. It will mux in mkvmerge without error and look fine in mediainfo but when played in MPC-HT it will show a black screen. If you click in the seek bar it will churn through the file and play after a minute or so, but this is abnormal behaviour. MakeMKV throws an error as well and refuses to mux it. Anyone else experience this or have a solution?
