I know Hi5 is probably not something you are too worried about
maintaining quality on, but re-encoding twice is not a particularly
good option.

On the avidemux forum there are posts about transport streams not
opening properly. I don't have time to go through all of them right
now. I suspect you need a recent (read development/beta/whatever)
version.
