If you install Qt Components, you should be able to get the "master" branch working too (there might be some fixes wrt Harmattan vs Fremantle necessary, but nothing too difficult). Even on Harmattan we then decided not to have video playback in the application, so even there we now delegate opening/playing videos to the built-in media player (while still playing audio inside the app). If you go that route, I can help you by answering questions about the codebase that you might have. Also, we could merge the Fremantle-support patches upstream for integration into 3.x releases if you or somebody writes them.

Or go all the way and use Qt 5 (a port seems to exist according to http://wiki.maemo.org/Qt5-Maemo5) and Python 3 plus PyOtherSide (once you have Qt 5 and Python 3 running, PyOtherSide should be easy). Then you can use the cuatro branch + the new QML UI (http://github.com/gpodder/gpodder-ui-qml), which looks a bit like that: http://www.youtube.com/watch?v=iqphTKirkKw
