I'm capturing from PC, not a console. The source videos are in .avi format, some recorded from Fraps, some recorded from Roxio PC Game Capture, but both produce the problem when rendering a production. I have tried various source videos and receive the same problem each time.
The Skyping only took place during the initial error, Skype has not been active in the attempts to recreate the issue. I've tried disabling all other background applications as entirely as possible to ensure that Roxio is the only thing running, to see if it was a conflict with another application, to include web browsers, messengers, Steam, patchers, etc.
The program I'm using to do the actual rendering is VideoWave, the application that came packaged with PC Game Capture and launches when I select "Edit" from the splash screen upon loading the PC Game Capture icon. If there's another forum for that particular program, I didn't see it.
My experience posting on support forums is rather limited due to most of my issues being resolved simply by googling the issue and seeing other posts, so if the information I provided was lacking, sorry about that.
As I mentioned it's only the iOS and YouTube formats that freeze the computer, I can still publish Windows Media and DivX files, so it's not like the program is unusable
