I have posted the replacement MPSA.ax for testing at...

Just drop it in your Windows/System32 folder (Renaming the old one) and rescan your channels.
I'm currently running it with MP 0.2.0.4
I have given it a go, re-scanned and the channel order is still the same (I think) as before. It is still in a very strange order that would require manual tweaking.
