Language / tips for a westerner learning polish? [5]

i've decided to learn polish. my family lives there and my father was born there, but he never taught me. i'm sure many westerners here have learned the language but i am not sure i'll ever be able to master it. i've found some lessons on youtube, but it seems that i can't even comprehend it and i cannot discern one word from the other. the language just seems to come out as noise. can anyone point me to some good free lessons? i know english and french and i was able to learn french with relative ease and i am pretty apt when it comes to learning a new language, but polish seems to be on a whole new level.
