Hauppauge HVR-1600 is compatible with PAL-M (Brazilian system)?

I have posted some problems i am having with my HP Pavilion Media Center
m7763w (Vista Home Premium, AMD 64 live +4600, 2GB RAM, 400GB HD, etc),
regarding the TV card (it is a Hauppauge HVR-1600):
1) MC does not recognize it, then every time I turn on my computer I must to
restart the service (Windows Media Center ...) in the Administrator option.
All I have tried did not initialize it automatically. Doing this the MC
works.
2) FM is ok, but the broadcasting TV shows a line horizontally below of mid
screen. All drivers are updated (video and HVR-1600 cards)! I guess it
could be a compatible problem, like a PAL-M incompatible system. I was not
able to find any information regarding the system it is compatible (SECAM,
PAL-N, PAL-M, NTSC, and so on).

So, if anybody know if this card is or not, PAL-M compatible, or if there is
any solution (like a firmware update) instead change the card, please let me
know.

Thanks
