Dan,
     My only experience with the rebuild issue is with my own h.264 
HDPVR recordings. I don't know if the issue applies beyond that video 
encoding type. That being said I have not spent much time looking for an 
alternative.

What I do know is that mkvmerge, Avidemux and maybe even ffmpeg (avconv) 
can determine a videos keyframes. I did spend a limited amount of time 
trying to see if I could extract that keyframe data out of an Avidemux 
"idx" files but could not figure it out. I also asked on their user 
forum but received no answer. Now with Lossless Cut I have abandoned 
Avidemux as it cannot delivery what I have now or that is what my ego is 
telling me;)

What you ask for would be useful. I communicated with the MythTV 
developer about the rebuild issue and he will fix it sometime in 
December. Right now he is over-abundant at work.

My advise is to hold-on until December or see if ffmpeg (avconv) can 
dump out the info in some usable manner. mkvinfo is limited to mkv 
files. If you find something that is reliable please pass that on to me. 
I would have no problem writing a script to load raw keyframe data into 
the DB using the python bindings, I already have one I use for Lossless 
Cut testing.
