Re: KWorld TV878 TV Tuner problem
It might sound strange, but bttv is a little stupid when guessing what card/chip is installed. If 5 is definately good, maybe card=78 isn´t. My card is =37, and even so, when I tweak it to other values, some functionality still works. There are values that don´t change much, actually. Try to test other values for card=, but keeping 5 for the tuner. I´d do it manually, instead of scripting, but that´s just me.
I´ll check further and see what I can find.
good luck,
bruno

Yes, I have. But one thing I forgot to mention in my previous post is that
if I boot into windows, watch a channel, then reboot into linux, I can see
the channel last viewed under windows (but no other channel, and tvtime-scanner
detects no other channel). However, if I cold boot into linux,
tvtime-scanner detects
no channel and no picture is displayed.

According to http://www.bttv-gallery.de/ my card number is 78,
and tuner=5
-----------------------------------------------------------------
chips: 25878-13,
Tuner: TN 5V TNF-9831-B/DFF BG+DK checked
pcb: 878TV REV:D
sticker on backside: VS-TV878RF Made in Taiwan 04111260162
bttv0: Bt878 (rev 17) at 0000:02:0c.0, irq: 11, latency: 32, mmio: 0xef000000
bttv0: using: Jetway TV/Capture JW-TV878-FBK, Kworld KW-TV878RF
[card=78,insmod option]
bttv0: gpio: en=00000000, out=00000000 in=003fffff [init]
bttv0: using tuner=5
------------------------------------------------------------------
The KWorld card I have mentions "VS-TV878RF" on the box. Yesterday,
after some googling, I found out about the btspy windows utility. So I
used it to get info about the card. I found that the guy who mentioned it
(http://ubuntuforums.org/showthread.php?t=160271)
got exactly the same values as my run of btspy gave me.
So I tried his modprobe line (after rmmod bttv):
----------------------------------------------
modprobe bttv card=78 radio=1 tuner=38 pll=1 gbuffers=4 gpiomask=0x1c0007 \
audiomux=0x080000,0x000001,0x080000,0x080000,0x000001
----------------------------------------------
But still no progress.
I thought my tuner must be a different one.
So, I booted into windows, copied the frequencies of some
working tv channels and went to linux (cold boot) and created a custom
stationlist.xml
with those channels. After that I tried this:
-------------------------------------------------
for i in `seq 0 45`; do
rmmod bttv;
modprobe bttv card=78 radio=1 pll=1 tuner=$i;
sleep 1;
tvtime --frequencies=custom --norm=PAL;
done
--------------------------------------------------
None of the 45 tuners worked, i.e. tvtime could not
show any of those channels :-(
I am getting out of ideas and google is not giving out any new
information. Please suggest if I should try anything else.
Regards,
Santanu
