Even though this thread is a year old, I ran into exactly the same
problem.
I had dubbed some old vcr tapes into a stereo DVD recorder.
Didnt bother with a splitter Y cables, so I figured Id capture on the left channel, and use PowerDirector to apply it to both L/R.
Unfortunately it didnt let me.
I had to rip the audio from the movie file using one piece of software
(AoA Audio Extractor), resave it as mono using another piece of software
(Audacity), and finally load it back into PowerDirector
A simple 'Make Mono' in addition to the 'Mute Track' would have been
a huge time saver in this case.
Cheers,
Rob.
