I had a similar problem with my PVR 250 with the 0.2.0 series ivtv drivers.  
The fix in my case was to pass along options to the msp3400 module.

in /etc/modules.d/aliases :

  options msp3400 once=1 simple=1 standard=0x20

followed by the obligatory modules-update ; depmod -ae

This is the one that worked for me.  Note that standard=0x20 is for NTSC in 
the US.  PAL/SECAM needs standard=0x09 according to this link (read the Q: 
about tinny audio).
