If you can come up with a patch for the bug, we can get it fixed for
everyone. It just happens to be way down low on my TODO list since I
have only ATSC tuners, so it's not really affecting me.
It may not even happen in all cases, too. I tried doing a lossy
transcode on my dev box (making an MPEG-4 in NUV file) to see if things
worked, and couldn't get the invalid preview images, so it might be
fixed in 0.22-fixes and trunk. If you're still using 0.21-fixes, you
might want to try upgrading to see if it's fixed (and, if so, I'd
appreciate your letting us know--so I can take that off my TODO list :).
Then again, looking at the last time I saw this pop up on the list ( http://www.gossamer-threads.com/lists/mythtv/users/365971#365971
seems at that time, I thought it was only RTJPEG in NUV. (Can your
system handle encoding to MPEG-4 in NUV in real time?)
Still, I'd love a patch. :)
