cx23885 / DVBSky T9580: mpeg risc op code error

[Mark Clarkstone]

Hey folks,

I seem to keep getting the this error after a day or two with my DVBSky T9580.

The card appears to keep working regardless of the error but
unfortunately whenever this occurs the Sky (UK)+ HD box downstairs
goes completely bonkers (poor signal, blocking etc) until I tune to a
service or restart the box. I'm only guessing here but I think
whenever this happens the card must be sending some weird voltage to
the dish interfering with the STB.
