This is by far the best DVD compressor available for MacOS X. With the current exchange rate, this app is a bit on the pricey side for us USians (luckily I bought it when it first came out and the Dollar was actually worth more than the Euro), but that's hardly their fault. The new ARccOS features make this a must-have update. Love the progress bar in the dock icon too. In all, I couldn't live without this great app; many thanks to the devs!
