I can confirm what Alexander said:
v4l2-ctl -c video_b_frames=0 (no stream saved, although nothing
appears in the syslog which would
indicate a problem)
v4l2-ctl -c video_b_frames=1 (the stream is saved OK)
All of this with the latest kernel (2.6.27) and a Hauppauge WinTV PVR-150 MCE
(the version without radio tuner but with a MCE remote control).

PS: BTW it didn't work with ivtv 1.1.0 as well (or was this 0.10.x, it happened
about half a year ago).
