had this comment from Michael Stucky in July, after I
had added his suggested mkv output option to my
mythDVBcut script to enable it to cut HD mpeg
recordings, with which the mplex remuxer apparently
failed.<br>

should have mentioned above, once the file is in an
MKV container it is no longer in a format that
MythTV considers a "recording". In other words, it
is not editable or seekable as a recording. You need
to use "mythexport" or some other script like that
to move it to your MythTV Video library where you
can play, fastforward, rewind, etc. as you would any
imported video.<br>

Is that still true?<br>

Not entirely. I have converted a large number of
recordings to MKV and the ability to skip/fast
forward/rewind/bookmark/etc. is still available. It's just
necessary to run "mythcommflag --rebuild" on the file
after the change, to rebuild the seektable.<br>
<br>
However, despite having done this, my attempts to edit
these recordings with the built-in editor result in a
complaint that there is no seektable. I've been using
avidemux to cut commercials, instead.

<div> It is my understanding that running "mythcommflag
--rebuild" on an MKV will actually remove the seektable
from the database (at least that is how it worked for
MythTV 0.26, I have not tested it under 0.27 as I have
gone back to using mythtranscode). Thus, my comment to
John that the MKV files were not editable or seekable.
This was correct behavior (which could have changed for
0.27) since MythTV wasn't designed (this is my
understanding which could be incorrect -- and hopefully
someone more knowledgeable will correct me) to edit/seek
within an MKV container. </div>

My point is that they are always seekable in 0.27 (and were usually
in 0.26 as well), after the "--rebuild". They are just not editable.<br>
</div>
<br></blockquote><div>Maybe I need to define my terms... When I say the file isn't seekable I'm not talking about the ability to fast forward/rewind within the playback (which has always worked fine for all of the recordings that I have converted to MKV using 0.25 and 0.26). Seekable, the way I am using it, means the file has a seektable in the database, I know for a fact that when I was using 0.26 if I ran "--rebuild" the seektable that existed in the database from before the conversion to MKV would be removed because the recording/file was no longer editable/seekable by MythTV. Maybe that has changed since I upgraded to 0.27 and went back to using mythtranscode. So, does a seektable exist in the database for your MKV files after running "--rebuild" (which would imply that they are editable) or not? I suspect not, since they are not editable. The bottom line, going back to the OP's question, is that MKV files should be playable by the internal player but not editable unless something has changed since about July of this year.</div>
