@Stone: really 120 x 768? Or 1280 x 768...?
Under the line it makes no different, all you have to do is change the parameters a little bit.
So in case the video is really 120 x 768 and you what MediaPortal automatically switch to "Stretch" if a playback of such a video is started, just create a rule with the following parameters:
- Rule name: what ever makes sense to you (it only used in the log file and the switch message)
- Minimal Width: 120
- Maximal Width: 120
- Minimal Height: 768
- Maximal Height: 768
- Enable the checkbox "this rule switches to the following viewmode" and select "Stretch"
- the checkbox "this rule uses following overscan" can stay disabled if the borders of such videos are "clean". Otherwise enable it and set the value (in pixel) how much MediaPortal should "zoom into" your video to let this borders disappear.
