Welcome to the forums, tavasam
Full flash support will come to the eDGe but for now TV shows and movies you would have to download to your PC/Mac, convert to iPod video format, and then copy these to your eDGe (using a USB memory stick would work great).
For registration problems, contact Tech Support (

I've never used Fring, so hopefully another forum member will be able to assist you on this.
