[linux-dvb] dvb-kernel and NTSC: the come back ;-)

[Gregoire Favre <greg@magma.unil.ch>]

Hello,

I have just recompiled 2.4.21-ac1 with latest dvb-kernel and videodev in
the kernel (changed...) and really good new: NTSC works again!!!

Remaining problem is the impossibility to have a small xawtv using xv,
and Oops when trying to do fullscreen without:

ksymoops 2.4.8 on i686 2.4.21-ac1.  Options used
     -V (default)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.4.21-ac1/ (default)
     -m /boot/System.map-2.4.21-ac1 (default)

Warning: You did not tell me where to find symbol information.  I will
assume that the log matches the kernel and modules that are running
right now and I'll use the default options above for symbol resolution.
If the current kernel and/or modules do not match the log, you can get
more accurate output by telling me the kernel version and where to find
map, modules, ksyms etc.  ksymoops -h explains the options.

Exit 1

I have just tried to do fullscreen on the first DVB card without xv: it
works perfectly, the problem is only for my second card???

Is there a way not to reboot to have my video1 back?

An hudge thank for the come back of NTSC (I got lots of NTSC movies)!!!
