At first I hesitated joining this site but now i'm glad I did. I am happy to see you really do have thousands of downloads. I just downloaded the software I needed. The service is great. Thank you and Ciao!

I'm not sure why some people think this is a scam site because i've just downloaded many of my favorite TV shows! The members download area is well done. This was worth the few dollars it cost me!
