Really not sure what is wrong, I can leave it playing a encrypted

If you're feeling adventurous, you might try recompiling MythTV. In
mythtv/libs/libmythtv/dvbcam.cpp, function DVBCam::CiHandlerLoop(),
there is a usleep(250) which I suspect is way to low. The CI
specification (EN50221) says it's fine to poll every 100ms, so try
setting it to 90000 or so (this ain't 100% correct because MythTV might
still want the shorter timeout to read replies etc...but it's a start if
you want to spend some effort debugging).
I know this was a long time ago, but it might interest you that I got
two patches committed to the MythTV repo today which improves the loop
timeout, adds proper per-100ms polling and implements support for the
DVB time (all in all, those patches should help you).
Expect to see the new functionality in 0.21.
