Replay AV - nothing but problems! need lots of help

Ok here's my unfortunate mess i've gotten myself into: i spent $50 on downloading this program called Replay AV to record video and audio. I HAVE been able to extract audio from some videos, but so far i can't record any actual videos themselves. The videos i want are on imeem and band websites,not YouTube (which, i think might be the problem, but i don't know why).

Some sites,i cant get the url,like it doesnt show up correctly in my browser. But my main problem is,if a video does SEEM to work,i'll go to play it,and my iTunes will pop up but nothing happens,the video isnt even there. Then i go to the file again and open it through Windows Media which can't even play the file because it is an flv file BUT i converted it to mp4 and it still wont play.

Is anyone familiar with Replay A/V? Or maybe somebody knows of an easier (possibly free?) way i can record these videos,where they will actually play on my computer! Thanks!
