konttori's Media Converter is working (Windows) but there was (for me) a wrong path in .bat file. After correction OK.

konttori is using in his Converter an adjustable videobitrate but with max 300 kbps. Mpeg1-video which is about 1150 kbps as standard is supported by the 770. There is unfortenately some annoying extra softness on 770 display because all videos (e.g.
352x208) are stretched to 800/600 x 480/360 which make comparisions quite subjective.

Is 300 kbps some kind of practical/theoretical/official max. videobitrate for the 770?
