Ok. Here's what I've managed to try so far. The following is with
modprobe tuner type=5 debug=1 pal=b (for Phillips PAL tuner)
modprobe saa7134 (with some debug options)
kernel 2.4.17-0.12 (redhat rawhide), v4l2 patches, saa7134 ver 0.14
------------- from dmesg --------------------------

-------------------------------------
However, when I tried to use xawtv 3.69 or even scantv to check
for TV signal, I still could not get any picture, scantv says 'no channel'
Incidentally, scantv doesn't recognize Composite0 as an input option, I
hacked scantv.c to do so to avoid the initial warning that it gives trying
to look for the 'television' input.
Trying other tuner options such as for TEMIC sometimes froze the box such
that a hard reset doesn't always recover. I had to remove the Flyvideo
2000 card first and reinsert it into the PCI slot before the system
can be cold-booted again.
At this point, I'm a little lost.
Questions:
1. In the CARDLIST file (patched for saa7134 v 0.14), what do
the model numbers (e.g., for type=0, Temic PAL (4002 FH5)) refer to?
The TV tuner block, or the ICs used in the tuner device?
[I ask because I can't find anything that matches against that list]
2. Should I try tuner types such as for Temic, ALPS, etc. or should
I only try the Phillips tuner types as the ICs in the tuner block
has Phillips TDA9800T and TDA6503AT devices? (Tuner is for PAL BG std)
3. I usually try the different options by doing 'modprobe tuner; modprobe
saa7134' then if it doesn't work, 'rmmod saa7134; rmmod tuner'
(I don't have the script in front of me, but it's done in the correct
sequence that avoids the 'module is busy' message). Would this
be sufficient or do I need to deal with the i2c, videodev, etc.
modules as well?
4. I can modprobe almost any tuner type and the dmesg output indicates
that the specified tuner is registered. Does it mean it actually
detected that the given tuner type exists?
5. Sometimes when I try some of the tuner options, the system will
hard-lock, to the point that the system cannot cold boot. Is this
'normal'? I hope I don't mess up some EEPROM somewhere that
prevents me from recovering even with removing the FlyVideo card and
reinserting it. (also, I'm wondering if the RF input signal generates
enough current/voltage to latch the devices in an unknown state)
Hope someone can shed some light on this.
Thank you so much and regards,
T.C.
