The only module you should ever load is "ivtv".  All other modules will 
be loaded by ivtv (assuming you load ivtv correctly--using modprobe and 
/not/ insmod).

msp3400 is the driver for the sound processor for PVR-250/350.  The 
PVR-150 uses the cx25840.  Therefore, if you load msp3400, at best, it 
wastes memory and at worst, it causes conflicts.

modprobe ivtv

and make sure you have the right module options.  For 0.3.8+, that 
should mean that you have no options specified for ivtv modules (it will 
autodetect.
