I have recently received a DVD from a relative. It holds some video clips showing my grandparents back in 1926 ! The person who did the conversion has done this without "unmirroring" them, so that license plates on car are inverted, and cars seem to drive on the left side as in UK. Is there a free video tool or web service that would allow me to mirror them, if possible without re-encoding them, since the quality is already low.
If you have already used such a tool, and were satisfied with it, could you recommend one.
In total, I have 7 clips, totalling around 200MB in DVD compliant MPEG2.
