Hi Everybody,

Has anyone got a KWorld Xpert PCI TV Tuner card (VS-TV878RF)
working under Linux. I would be grateful if you could let me know
how to get it working under Linux.

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.
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 have also tried all the cards (all 120 of them) with the tuner=5
option. No progress.

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 Chatterjee
