I am about to give up with this KWorld card as I do not have the time - 
I need to get something that works.  So 2 questions - one for a 'last 
try' and one for 'Plan B'.

Q1. Initially, the card was not recognised automatically, but under 
guidance form Hermann, forcing Linux to treat it as card=114, I was able 
to capture video.  Unfortunately, normally Black and White rather than 
colour.  I understand that  normally Linux would sniff the eeprom and 
determine the type of card from information found in there.  I have the 
.inf files that describe the various KWorld cards to that other 
operating system and I can see that the first 4 bytes of the eeprom, 
albeit swapped about (Big Endian/Little Endian) are used in that .inf to 
identify the card.  Various parameters are apparently put into the 
Registry, depending on the card type and I thought I would compare the 
parameters for my card with the parameters for the 'Real 114'.  I assume 
that there is a file somewhere which says "If the eeprom says 'xxxx' 
then the card is type 'n'".  Where can I see that file which identifies 
the card type?

Q2. Assuming that I am unable to make any difference, I will need to use 
a different card - and hopefully, one that is supported.  In order to 
make the current card do anything, I had to issue a couple of commands

"modprobe -vr saa7134-dvb saa7134-alsa saa7134 tuner"

"modprobe -v saa7134 card=114 i2c_scan=1"

so presumably, I would need to 'undo' the effect of those lines to let Linux auto-detect.  What do I need to do?
