Thanks to everybody who's responded so far. I've made progress. It turns 
out that I swapped the blue and green lines (TWICE -- it's dark behind 
my AV stack!), and this seems to have confused the HDPVR. I can now get 
a video file when I do a "cat /dev/video1 > foo.ts".

MythTV is still giving me 0-length recordings, though. I expect this is 
some silly problem in the MythTV configuration, so I'll review that 
later this evening or tomorrow.

At least I know the hardware's OK. (I hate having to return things!)
