The reason it does this is that the backend expects to see a stream from the 
dvb card without the scrambling bit set. Unfortunately as your card cannot 
decrypt this stream, the stream never arrives. The backend then sits in a 
read loop dropping the packets repeatedly. I see a similar problem in 
Australia, however as almost all of the channels I dont pay for are 
permanently scrambled I just delete them from the db.

It is possible to fix this, however it requires a code change in the 
dvbrecorder code. This might be something I can have a look at but I can't 
guarantee a timeframe for a patch. Probably some type of osd window with 
'Channel Scrambled' and a clean exit of the tight read loop without exiting 
liveTV should do the job.
