I occasionally use TMPGEnc to transform a QT trailer into an svcd-ready mpeg that I can use to make a trailer svcd compilation for my dvd player.

But in a few cases TMPGEnc refuses to open the triler, says it's unsupported. Most recent case: the trailer for Highwaymen from Apple's site.

Does anyone have any idea why TMPGEnc refuses to accept this one?
