There is no way to check sanity of the MPEG stream before passing it to 
the ARM. What frontend are you using? The stv0299 is known to produce 
garbled transport streams at poor receiption.

The L64781 should pass only valid TS data, maybe my last commit 
configuring the L64781 to another stream mode broke this. Please try to 
revert my commit from 2002/11/21 11:27:28 and report if this solves your 
problem.

The kdvb-fe thread is intended to check the frontend status regulary and 
shut down the ARM when the TS is not known to be stable.
