HTC Touch HD provides undeniably one of the best screen estates for film viewing against every other phone (Windows Mobile or not) out there. Unfortunately, users of Touch HD reported having massive problems getting a decent video playback from their devices, due mostly to the encoding settings they use.
Projection, from xda-developers is developing a tool that will help make video encoding for Touch HDÂ very easy. The application that works on Windows,Â will encode in a few simple steps your video file to the most suitable format for Touch HD.
The application is still under development so there are a few issues that needs to be worked out, but the feedback is positive already, so it sounds like a promising application.
You can try or follow the development of this application here.
