Bug 446062

SUMMARY
kaffeine worked with my DVB-T card, but has stopped. I may have updated software as I do regularly, but cannot recall what was updated.
kaffeine "recognises" my card according to the log, but then states the device hasn't been found!
me-tv works with the card.



STEPS TO REPRODUCE
1.  Run kaffeine
2. Go to Television "button"

OBSERVED RESULT
Notification that "Device not found"

EXPECTED RESULT
Being able to access DVB-T card

I also installed me-tv, and the card works with that.
It has only been the past week or so that kaffeine has stopped working with my DVB-T card (a Hauppaugge 1300 card)

Please let me know if more information would help.

My apologies if I am being a numpty, but I am stumped! Sorry!
