[linux-dvb] Nova-t problem

[Mike Ryan <mike.ryan@redmar.com>]

Hi

Apologies in advance for the long post, but I've been struggling with this for a
while now, and wanted to include as much information as possible.

Anyway, I installed a Fedora Core 2 system and upgraded the kernel to 2.6.7
without problem. At this point, I followed the instructions here to install the
DVB-T software:
http://www.comp.lancs.ac.uk/computing/users/leek/ukdvb.php

cvs -d :pserver:anonymous@linuxtv.org:/cvs/linuxtv login
cvs -d :pserver:anonymous@linuxtv.org:/cvs/linuxtv co dvb-kernel
cd dvb-kernel/build-2.6
./getlinks
make

cd dvb-kernel/build-2.6
./insmod.sh load

This created the drivers for me and loaded the modules
Devices created:

After running insmod.sh, this appears in the /var/log/messages file:

I was able to use dvbscan without problem to build a channels.conf

Also, tuning seems ok:
[root@linuxpvr szap]# ./tzap "Channel 4"
using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0'
reading channels from file '/root/.tzap/channels.conf'
tuning to 481833330 Hz

Also (as long as I'm running tzap at the same time) I am able to use dvbdate
[root@linuxpvr dvbdate]# ./dvbdate
 
Tue Jul 27 21:09:07 2004
[root@linuxpvr dvbdate]#

I also verified these were coming over the UHF cable, by trying them with the
aerial unplugged and as expected they failed

Unable to view anything. Someone suggested running this while tzap was running:
[root@linuxpvr build-2.6]# cat /dev/dvb/adapter0/dvr0 > video.ts
 
[root@linuxpvr build-2.6]# ls -lsa video.ts
0 -rw-r--r--  1 root root 0 Jul 27 21:18 video.ts
[root@linuxpvr build-2.6]#

However, as you can see, nothing is generated

When I try xine dvb://, I get the following error message:
There is no input plugin available to handle 'dvb://'
Maybe MRL syntax is wrong or file/stream source
doesn't exist

My local transmitter is Crystal Palace, and I found this command to tune to and
view BBC1. Unfortunately, nothing seems to happen and I have to Ctrl-C out of
it.

I have also physically removed the card from the system to confirm what model it
is. 
It's a Hauppauge WinTV-NOVA-t Version 1.20 and the two onboard chips are
labelled L64781 and Philips SAA 7145A H, as was logged in the /var/log/messages
file.

So, has anyone got any suggestions to where I can go from here? I had a feeling
that firmware may be an issue that I'm missing here??? This particular line
from the messages file does seem odd:
Jul 27 21:05:06 linuxpvr kernel: mt312_read: ret == -121

Thanks in advance for any suggestion anyone may have

Regards

Mike
