Hi, I think u would have not scanned for channels which is veryimportant. Execute "scantv -o .xawtv". U'r arguments to "bttv" and
"tuner" driver modules is not correct.Follow the steps in the attachment. Confirm the hardware by executing "xawtv -hwscan". With Regards, S.Suriya Mohan. India. On Mon, 07 Jul 2003 Donald Tournier wrote :
Hi,I'm trying to get my newly purchased Pinnacle PCTV pro card working
under
Linux. It works fine under windows, although it took me a while to
work
out that I was supposed to use the PAL-I standard since I live in the
UK.
Under Linux, it looks like the modules work fine, but xawtv displays a blue screen. I read somewhere that this means that the card works
fine but
needs further configuration. I'm no expert with TV cards - this is thefirst time I try one. Maybe someone can help me to find the
appropriate
settings?I've attached all the information about the system that I thought
could
possibly be useful at the bottom of this email. Thanks for your help, Donald. ====================================================== uname -a ======================================================Linux linux 2.4.20-4GB-athlon #1 Mon Mar 17 17:56:47 UTC 2003 i686

Quick TV Card Configuration Guide for Linux HOME
By Manish Kumar Arya
Requirements
Check for TV Card on Machine
A TV tuner card is installed on PCI Slots on Computer. To check for TV Tuner Card on your Computer run 'lspci'
$lspci | grep -i bt
[root@manish manish]# /sbin/lspci | grep -i bt 01:0a.0 Multimedia video controller: Brooktree Corporation Bt878 Video Capture (rev 02) 01:0a.1 Multimedia controller: Brooktree Corporation Bt878 Audio Capture (rev 02)
basically bbtv can work for Bt848 and Bt878 chip sets and some other chip sets also
another way to check for TV card prsence is to use hard ware detection option of xawtv program
run $xawtv -hwscan
[manish@manish manish]$ xawtv -hwscan This is xawtv-3.73, running on Linux/i686 (2.4.18-3) looking for available devices port 67-67 type : Xvideo, image scaler name : I810 Video Overlay
/dev/video0: OK [ -device /dev/video0 ] type : v4l name : BT878(Pixelview PlayTV (bt878) flags: overlay capture tuner
if you able to find TV Tuner card on your PC then you need to specify many parameters for bttv driver module to correcty work for your card. These Parameters are
1.Card Type This is basically your TV Cards Brand Name and model name and can easily be know from manual of you TV Card A complete list of cards supported is listed in '/usr/src/linux/Documentation/video4linux/bttv/CARDLIST'
2.Tuner Type for this you need to reffer manual of your TV Card or open your PC cabinet, plug out TV card and check names like 'Philips, Tunic, Alps, LG'. A complete list of supported tuner can be found in '/usr/src/linux/Documentation/video4linux/bttv/CARDLIST'
Configuration
now make a shell script that will load drivers for TV card
#!/bin/bash #load_tv_drivers /sbin/modprobe tuner type=5 debug=1 /sbin/modprobe bttv card=16 audiomux=0 automute=1
lets analyse above script word by word
/sbin/modprobe this command is used to insert loadable kernel modules including supporting modules.Tuner is the name of driver for TV tuner and it is loaded for tuner of type 5(see '/usr/src/linux/Documentation/video4linux/bttv/CARDLIST' for tuner types like 5 is for Philips PAL) and debug=1 turns on debuging
bttv is
main kernel module required for TV card to work option "card=
For more options for modules reffer '/usr/src/linux/Documentation/video4linux/bttv/Insmod-Options'
You can save above script and call it from /etc/rc.local to load drivers at boot time by adding a line in /etc/rc.local
/
an alternative to this way of loading modules is to add an entry for your TV card drivers in /etc/modules.conf
Now you are ready to launch TV viewing program
on X-window run xawtv from a terminal (like xterm)
now tune channels run scantv command
$scantv -o .xawtv
it will prompt you for for TV norm selection select one like PAL TV norm works in India next you are prompted for frequency table select one according to your geographic location, if you dont find your location in table list dont panic, try existing some other frequency tables. like for India europe-west works
.xawtv file is default setting file for xawtv program for a user. To make a global file you can specify /etc/xawtvrc file in scantv -o option
if you are not able to tune channels in first go, dont give up try other frequency tables and/or TV norms
once you have tuned channels, next you need to give some name to channels(optional) and fine tune them( if needed) some weak signal channels are missed during scan. You can add them later
for feedback and correction please mail to manish@xxxxxxxxxxxxx
