[linux-dvb] Twinhan VP1041 and 64-bit FC6 troubles

Gernot,
thanks, I have tried your second patch from 
http://pansy.at/gernot/twinhan-vp1041-2.diff.gz
and could successfully see one dvb-s channel on my Twinhan VP-1041, but when I use szap -r to view the channel it hangs in a way that I can't kill (it becomes a process in state D, i.e. uninterruptible sleep). So I can't 
change channels and have to reboot. I didn't try dvb-s2 yet.

Here is what I did -- perhaps you can see something wrong:

a)kernel 2.6.20 stock ubuntu feisty, amd-64bit

b)used your patch to patch multiproto commit 0f3e5ce65e32

c)there was one file missing from your patch (cu1216_regs.h) so I copied it from the driver on twinhan's website v1.4.2

d)compiled patched multiproto and installed successfully

e)obtained scan from http://jusst.de/manu/scan.tar.bz2 and slotted in the util/scan directory of hg http://linuxtv.org/hg/dvb-apps/. I fixed up the .h includes to come from the earlier multiproto compilation.

f)obtained szap.c from http://abraham.manu.googlepages.com/szap.c and compiled it in util/szap according to
http://www.linuxtv.org/pipermail/linux-dvb/2007-October/021474.html

(messy -- is there a "dvb-apps for multiproto" tree somewhere?)

scan seems to work fine to create a channels.conf.
Then to view a channel I did:
szap -r -a 0 -l UNIVERSAL -t 0 -c channels.conf "channelname"
and then
mplayer - < /dev/dvb/adapter0/dvr0

szap tunes and locks and I get video and audio from mplayer but after that I cannot kill it (with ctrl-c or kill) to change to another channel.

Any idea what's wrong?
What's the best way to view channels?
Are you merging your code into multiproto?

Regards,
Hans
