Summary: 5 second frame timeouts on weak channels with bt848/wintv

Initial Comment:
videoinput: Can't wait for frame 3: Interrupted system call

    Your capture card driver: BT848( ***
UNKNOWN/GENERIC **)
    is taking too long to provide frames to tvtime. 
...

I get the above error on weak channels. Most chans are
fine.
The frame number varies from 0-3, as I use
modprobe tuner type=2; modprobe bttv gbuffers=4


dmesg (for inserting the modules) follows:

Is this still an issue?  I am annoyed that the driver will
block us for so long, I wish they had a maximum timeout of
one field's worth.  I wonder if we could do anything better?
