I can also confirm this. I have Ubuntu Jaunty witl all updates and Pinnacle PCTV Studio/Rave tuner (on PCI).

When I run Zapping, I got two errors:

Cannot restore previous mode:
/usr/sbin/zapping_setup_fb failed.
DMA is not possible on screen 0.

and

Cannot start capturing: /build/buildd/zapping-0.10~cvs6/src/tveng25.c:map_xbuffers:2578: ioctl VIDIOC_REQBUFS failed: 0, Success

However, XawTV is working fine.

P. S. While running zapping_setup_fb from command line, I got this:

Can please anyone repair this, since there is a real lack of analog TV viewing software in Linux? Thanks.

I have the same problem on jaunty. I can't install newer version of Ubuntu, because of problem with my ATI Radeon 9000 (totally black screen when system is loading).
Is it possible to run Zapping on Jaunty? Have anyone solved this problem?
