DVD of POTOP (1974) trilogy - where to buy it?

Hello , would somebody help me?

I would like to buy a DVD of POTOP (1974) trilogy...I tried, Amazon, they only have
Region 1 (usa and canada) and need an european code.

I would like english subtitles, because I don't speak polish.
If someone can provide a website or an address where I could
order this DVD I would be very grateful.

You need 'Merlin' internet shop.

it looks like the Polish edition of the Trylogy is without any subtitles, and sound is only in Polish too, at least the description on Merlin (and I also checked vivid.pl) doesn't mention any other language versions, but maybe someone has those discs and can confirm?

The only place I saw this today was play.com.

I didn't see any relevant details though.

Thank you very much.
But the dvd on play.com also has only Region 1 version....

Maybe I will settle with a no-subtitles polish version...I mean
I don't speak polish, but I understand enough to folow the plot...

You can make your dvd player regio free. Google is your friend! :-)
