I just checked & avast! Antivirus didn't report anything. Google has probably listed the site as malicious because the program can unlock DRM protected media. Use it at your own risk.
Ironically, you'll see the Google icon at the bottom right of the page!
I have an .avi file, it's 788 MB, I drag it to iDVD, let it encode, burn, and when I pop it in, it stops at 25 mins. I have tried single layer and double layer dvd-r's. I am using last year's model macbook pro
