I have to say, I installed Videora on Windows for a relative (wanted to convert a home movie to her iPod Touch) and the app is so bloated with ads that I wanted to slash my wrists after 2 minutes. I've heard rumors that the ads can be turned off, but I couldn't find it.
I JUST WANT TO CONVERT A FILE.. BUGGER OFF WITH THE ANNOYINGLY PLACED / OBTRUSIVE ADS!!
So much so I ended up converting the movie on Visual Hub and taking it over on USB stick.
