I have done that while installing vdr 0.82 and the latest CVS driver.
I also still have EPG scanning disabled.
Here is what happens:

I am seeing 4 problems in the log above:

1.  cDvbApi::SetPid issues an error message for 
    the DMX_SET_PES_FILTER ioctl:
    Jun 17 16:39:20 vdr vdr[18454]: ERROR (dvbapi.c,2052): Device or resource busy

2.  During every recording I am getting "read incomplete section" errors.

3.  The "emergency exit" is not taken after its first initiation,
    it hits about 20 times before it really exits.

4.  The driver tries to vfree a bad address.


Any ideas?


Carsten.
