Sorry, I misread it as 2450 rather than 2540.  I've just checked and the
firmwares for both the 2000 and 2450 are versioned 2540.  I've also had a
chance to build dvb support into mplayer, and it tunes and plays fine for me.

I have found one thing that doesn't work - USB 2.0 ports.  Those fail at
ttusb_dec_start_iso_xfer because split iso transfers are still in development
in the EHCI driver.  The error number is 38 so I'm guessing that is j's
problem:

Not sure why nothing is appearing in the kernel logs there - it should be.  If
you're using USB 2.0, you can try turning on 'Full speed ISO transactions'
under 'EHCI HCD (USB 2.0) support' in the kernel configuration.  It's an
experimental option so you will need those turned on.  It doesn't work for me
(enomem error, not sure why yet - I will have a proper look), but it may for
you.

j - have you had the oops since updating your cvs checkout?  mplayer seems to
stop the streams despite them having failed to start, which is why you were
getting it I suspect.  If the driver is still oopsing, it needs to be fixed.

Cheers,
Alex
