I bought Power Director (Cyber Link) through HermanStreet and found that when I imported an avi file, for example, into Power Director and completed my editing that I could not then export my video file back out to my hard disk as an avi file. They only export their own proprietary vob file. I could convert this vob file to avi, I suppose, but I didn't pay over 90 bucks including a cd for a program where I have to do the extra step. Cyber Link tech support admitted that it can only export vob and apologized for the shortcoming.
Maybe I'm out of touch but I thought I should get a refund but was blown off by the Herman Street support guy.
Needless to say, I will not buy from them again!
