[mythtv-users] Are transcoded files supposed to play in mplayer?

[Brad Templeton]

I recently transcoded a variety of shows using the internal myth
transcoder, scaling down to 352x480 mp4 from pvr-250 recorded mp2 files.

They play fine in myth's internal player, but I had intended to move
them over to be long term videos, and I find that mplayer has all sorts
of problems with them.  For one, the aspect ratio is lost, so you have
to tell mplayer the actual aspect ratio, but more importantly not too
long into the videos mplayer crashes, with output similar to what is
seen below.

Are these transcodes expected to play in mplayer?   My goal for
recordings is to keep them around as full size mp2 for a while, then
transocde them down to smaller mp4 (but still in the regular myth
recordings) and then to later move some of them to longer term holding
in the mythvideo directory or dvd.

I seem to recall this working before, is something new happening because
of the scale-down?   Since the general impression is that ntsc doesn't
deliver much more than 352 pixels wide, it seems like a good idea to scale
long-term recordings down to that.
