the whole point of playing 720p on your n900 is that you don't have to convert it. If I have to go somewhere by train for example, it would be nice if I could just put my freshly downloaded 720p vid on my phone, and not wasting any time converting. If I had to convert all those movies/tvshows, I'd be wasting months of times and gigabytes of hdspace.

I have more space on my phone than I have time for converting.
