Look at the channel listings in the NFPS Private Server forum. If you find your polish channels, you can get them on any of the three P$ supported here. We generally recommend Rocket.
I just scrolled through the entire list on my AVOV box and did not see one Polish channel. Whether it be Rocket, NFPS, or 66, the channel line up will be exactly the same as these are all retailers of the same exact service.
Since you have an AVOV box, you can go to the MickyMart and download Dream IPTV. It has 16 Polish channels and it's free. Sometimes the channels will play and sometimes they won't, it's a crap shoot, but it's the best you'll probably get.
