Very useful, I was able to watch a couple of DVDs and TV programmes on a recent flight!

I did find a couple of problems with some conversions. In one case, converting a DVD, I got the German rather than English soundtrack. In another, converting a TV programme (recorded on a Topfield PVR), the audio description track was picked rather than the normal audio. So, any hints on how to work out how to specify the correct audio track, when the default settings don't work? (In most cases, for both DVD and recorded TV, the default options for tablet-encode worked fine.)
