I think I have tzap working, but I can't run xawtv. I get messages like 
the following:

can't open /dev/v4l/video0: No such file or directory

I have no /dev/v4l. I wondered whether I was supposed to use the video 
devices under /dev/ost instead, but "xawtv -c /dev/ost/video0" didn't 
work either. Assuming I need the v4l devices, I tried MAKEDEV v4l (this 
is Mandrake 9.0, which uses devfs and their own modified version of 
MAKEDEV). This gave the following error

MAKEDEV: error making /dev/dcxx0: Operation not permitted

after which it exited, having created a /dev/dcxx0- device, but none of 
the other devices. I assume I need to do something to get devfs to setup 
the v4l device files, but I haven't got a clue how.

This is all on a recently compiled kernel (2.4.20-2mdk with recent 
supermount patch and mod_dvb replaced with 20021229 dvb modules). v4l 
(-2 with -1 compatibility) is compiled into the kernel. I've run "make 
insmod" to setup the ost devices.

Once again, I feel I am missing something obvious, but I can't find any 
HOWTO or man page to guide me through this. What am I doing wrong?

Cheers,

Bruno Prior
