i find that my plain credit card works easy. I don't need a paypal account etc. So to me CC was without a doubt the easier method.
Playon and Playlater (Once-off payment of $59.99) allows you to run a Play server which other devices access and stream content through (IOS, Android, Xbox, PS3, etc). Playlater allows you to record (download) shows which is great.
I use it to record shows that my girlfriend watches so I can play games without my ping being affected as she watches recorded shows on the Xbox.
Playon / Playlater has a 30-day money back guarantee so there is no harm in trying it guess.
Big ups to Mike already as he has provided loads of info on this thread. I am not sure what other feedback you may be waiting for?
