I don't run xine, so that wasn't likely. I gave it a shot anyhow and
it changed nothing.
Further poking around turned up this HOWTO on installing myth on Fedora
Core (which I'm not running, but there's enough relevant information
I had tried dd'ing /dev/video0 directly to /dev/video16, and got the
same result as watching live TV or recordings in myth. Running this
command from that HOWTO got playback working:
ivtvfbctl /dev/fb0 -noglobalalpha -localalpha
Unfortunately, now myth's own menus were invisible. Reversing the
ivtvfbctl /dev/fb0 -nolocalalpha
made the menus visible again, but now a double of the image is offset
half a screen width to the right.
It would seem mythtv-0.15.1 is doing something different with the alpha
controls compared to 0.13, which did not exhibit this problem.
