Sorry, fhfreak, but I don't use PowerDVD so I don't know anything about it.
As to address some issues that have been mentioned, our space is upgradeable at anytime with one click of a mouse. With my Hayden Media site, I'm currently using 1.85 GB worth of space, and when I came close to my 1 GB limit I posted a space request, and she upgraded me.
As for programs, I use a program called Media Player Classic, which in my opinion is much easier than some of the methods previously mentioned. I use this program for all my screencaptures.
If we wanted to move forward, I could figure out the logistics for this to work. Maybe we could setup an FTP account for just screencaps? This might be easier...
