Problems with PVR 250 and MythTV

[Greg 'groggy' Lehey]

Sorry, I can't find a way to reply to the messages that have gone past
overnight, so I'll start again.

* The PVR-250 is an analogue card.  If you're feeding it a digital
  source, you won't get any signal.

* Before you can use the card, you need to tune to a signal.
  Currently the program pvr250-setchannel does that; effectively the
  same program exists in 7-CURRENT as setchannel, and I'll MFC it when
  I'm happy with the rest.

  Tune like this:

     $ setchannel -m <channel-set> channel-no

  If you're in the USA using terrestial TV, <channel-set> is 1.  Cable
  is 2.  If you're using a satellite connection, you'll need some kind
  of converter.

  I'm not sure about the status of the man page for setchannel, but if
  you run it without arguments you should get a help message.

* The current driver from usleep doesn't report errors when you try to
  tune to a channel without a signal.  The old one (multimedia/pvr250)
  did.  This is on my "to do" list.

Once you have tuned to a channel, you can cat /dev/cxm0 somewhere.
After that, you're in a position to set up MythTV.  I'd strongly
recommend using a terrestial source first to confirm that your card is
working properly, then investigate the satellite input, and only then
fighting MythTV.
