I have been playing with Handbrake for most of the evening and one thing that I'm just not getting is how I can bump up the resolution. The source is showing as 720 x 480. If I don't change anything I end up with a movie that fills the screen but everything is ever so slightly stretched...it's not a ton but I find it distracting watching the movie this way. If I check Keep Aspect Ratio I no longer have the stretching but the movie is significantly smaller and I have larger black bars.
Part of what is perplexing me is that I had converted a movie for my Android phone which fits the screen very nicely on the Nook. It's possible this was not a wide screen format movie...but I also have 3 other movies I got from another source and they also fill the screen nicely...I suppose it's possible they, too, were not wide screen.
Anyway, if my original movie is only 720 x 480...how are you bumping UP the resolution?
