[linux-dvb] Re: xawtv-3.88 with SAA7146(KNC1)

["Doug You" <doug.you@pebblevoice.com>]

Thank you very much Michael. I've downloaded it from Metzler Brother's
1.1.6b version for my KNC1 budget, which looks working almost as far as
xawtv's up and running with some error messages that I noticed.
#xawtv
/dev/video0 [v4l2]: ioctl VIDIOC_QUERYCAP: Invalid argument
ioctl: VIDIOCSFREQ(long=-1): Invalid argument

Sounds like issues on iocontrol of tuner module probably, and thought I
could narrow my job to tuner module.
someone also mentioned it at Google, it caused by picking up wrong tuner
parameter in somewhere in code.
am I correct assuming this approach? any comment would be appreciated.
Many thanks to you and other gurus.
