*** Bug 108708 has been marked as a duplicate of this bug. ***
I need a sample file, could you please report the issue upstream if it does apply to the curren cvs version?
I can't give you a sample file, as it would be a copyright violation, and I don't know how to encode video into this format. This is not an upstream issue, mplayer doesn't support mythtv nuv files, the mythtv USE flag applies a gentoo patch.
Please try upstream CVS. About half of gentoos mythtv patch was cleaned up and applied. The rest was too much of a mess to be integrated cleanly.
Forgot to say: you can also use dd to extract only a small part of the file, that contains just a few frames (but check if it still shows the same problem). When this works, it is always preferable to a full file. My understanding is that this should also fall under some kind of fair-use rule and not cause a problem copyright wise. Depends of course on the country you're in etc.
Please test latest.
Sorry for the long delay. I tested it with the latest mplayer and it seems to be working fine.
