If having the SkyStar 2 installed and also having EPG turned on then you get no TV. Looking at the log it contains errors when the EPG thread starts.

h4. Steps to Reproduce
Add SS2 as a TV Card to Config
Enable EPG grabbing
Start MediaPortal
Start MyTV

You'll get no TV and it's impossible to turn it on.
Highlighting and trying to turn on the TV button sometimes causes an exception with the SS2's source filter.
