Hi James,

Two things - try turning off the setting 'wait for seq start header' in your 
dvb card setup in the mythtv-setup app. There is possibly a bug in the TS 
SEQ detection code that manifests this way.
Either that, or you are having a descrambling issue. I'm almost done with a 
patch against current svn that will restart the cam if you get a scrambling 
issue which has resolved this with an irdeto cam. I was experiencing a 
descrambling problem probably 3 days after a restart which is fixed by this
