Yes, that also fails.

Yes, those succeed.  So, that solves my problem, thank you.

I will switch to doing that, and update the MythTV wiki appropriately.  I
assume that this is the correct invocation for any similar capture devices,
not just the PVR-500 and family.

Ah, well then that part of my bug report was incorrect.  Sometimes shows
don't send caption data, even the same program one week later.  I happened
to have two recordings in standard definition that had no captions, but one
recorded last night did, as might be expected if MythTV already worked
around it.

Thank you for your time on this, Andy and Hans.  I will update my scripts,
and this will work perfectly for me.
