There are several tuner types that could match "a phillips one", even one 
you know uses NTSC. tuner=2 is one choice, but not the only one. Check the 
CARDLIST in your kernel-video4linux-bttv Documentation, as I suggested 
before, for the details.

On my (2.4.19, Debian package) kernel tree, it's the first item in the 
Sound menu ("BT878 audio dma") under a checked "Sound card support" item.

No thoughts here, I regret to say.
