Rotation of converted video...

I'm not sure whether this has been covered in another thread, but I just discovered for myself that there is no need to rotate the converted video as the Miniplayer automatically does it for you.

Now I don't need to break my neck to check my converted video on my computer screen!

Rotated videos play more smoothly and uses less processing power, or so we are told by Meizu.

I'd like to hear if anybody can notice a difference.

320x240 (20 fps, 128kbps mp3, ~350kbps xvid) video plays with 'lags' and syncs
converted to 240x320 via videoconverter plays smooth.
There si problem with mencoder and video rotation - rotated video have too high bitrate for player so you need to full reencode video for rotate it ... (or just rotate amd rencode it in one step)
