Odin7

I must agree. I have downloaded the latest version of Prism for PC. I am using Windows 7 and the SW converts the avi file to mp4 until exactly 4:56 into the video. Same exact symptoms. After that the converted video looks like a psychedilic array of colorful gibberish as a frozen image for the rest of the 2 hour video. It converts slowly and correctly until 4:56 then takes off filling the rest of the file with that gibberish image in less than 30 minutes. I have paid for this software (twice) and registered it and downloaded the latest version. If this isn't resolved soon, I will post images on Amazon with my 1 star review. I also have a chat open for 24 hours with Amazon customer service.

Exact same thing happens to me at about 6 minutes. (More exact details to follow)
