Video player on iPad that doesn't stretch to full screen I'm looking for a video player that doesn't stretch my 640x480 video files to full screen (1024x768), which degrades the quality IMHO.

Is such an app available?
OPLayerHD allows you to select the stretching mode, so you can select between full screen and actual ration of the video.

There is also a lite version, maybe you can try that one before buying the complete OPlayerHD

Alternativelly there was AVPlayerHD, which seems to be not available now.
