Summary: PAL video problems

Initial Comment:
I have a BT878 PACE TV card and for many years I have been unable to get PAL working with my TV card either using TVTIME or XAWTV.
The best I can do to get a stable picture for both TV applications but in black and white is using PAL-NC mode.
To illustrate the problem I've made 2 screen grabs from Linux Mint:

>From what I can tell it looks like a timing issue and do I seems to recall reading something about BT878 running on 2 different XTAL chips.
Is there anything I can do or test to try and get PAL working on my machine??

Message:
The settings for bttv needs tweaking because the card isn't detected
properly.
The follow commands corrects the PAL problem for my card:
rmmod bttv
modprobe bttv card=72 tuner=5

Message:
It's a tuner detection problem by kernel module.

You'll need to manually set module option in:
"/etc/modprobe.d/options" file.

In my case I had to append there:
"options bttv card=38 tuner=35"
to get my really old no-name TV card to work properly.
