Seems I'm having a problem with the following ...

I get ...
destination directory: v4l-dvb-experimental
abort: HTTP Error 404: Not Found
but if I can it to ...
hg clone http://mcentral.de/~mrec/v4l-dvb-kernel
I get source ...
> $ cd v4l-dvb-experimental
cd v4l-dvb-kernel
> $ make
and then sudo make install ... Would of prefered if I did not have to
over write some of my kernel, but I have the rpm to re-install if
there is a problem ... Could this not be made to install in updates or
something?

Okay ... Did a reboot just to be sure ... and then a modprobe -r
em28xx and modprobe em28xx ...

And record ... Now I get sound and good video expect the video is at
640x480 ... Are these devices only able to capture at 640x480? This
is an improvement, seeing that my captures with the stock kernel drive
gave me 640x480, but the video seemed to be missing 10% on the right
and buttom side of the video image ... This seems to at least scale
the video from PAL ...
My DC10+ can capture at PAL 768x576 and basic PAL is 720x576, can USB
capturing devices do this?
Thanks

P.S. At least I now should be able to run my basic tests with
ZoneMinder and the USB capture device ...
P.S.S. My system seems to be more stable with the update v4l ... Thanks.
