Yes, the two Hauppauge HVR-1600 cards and the Adaptec AVC 2410 card
works with mplayer.

When I booted the system to test this, I discovered that the
/dev/video* entries applied to the cards differently.  My Adaptec card
had been /dev/video1 the last time I looked but was /dev/video0 this
time.  That seems likely to mix up configurations.  This discussion
seems relevant, but I don't know how to use this since the backend
setup program only seems to accept pathnames from its list.  Otherwise
I could use these pathnames which have the pci-slot in their name (I
think):
    $ ls -l --color=never /dev/v4l/by-path/

I was able to set up one of the HVR-1600 cards using Card type "IVTV
MPEG-2 encoder" (I'm not sure how).  And it worked (for watching live
TV with Myth frontend).  But I tried a lot of things to get the second
card registered this way and failed.  One of those things was deleting
the good entry.  Too bad: I've not been able to get it back.

Thank *you*.

Oops: I was wrong!  I can type these oh-so-long names in by hand to
the backend setup program.  Just not the way I thought it would work.

Problems solved!  Thanks.

PS: it would be good if the pathname picker for the video interface
knew these absolute names.  That way people with multiple cards would
not have troubles with the names standing for different cards each
time the system is booted.

These pci-slot names are so long that some bits of the backend setup
GUI don't work that well.
