File Association puzzle

[Terry Pinnell]

I had problems with the MP4 association (I think an audio player somehow
took it over from WMP). Anyway, at some stage I had no entry for it in
File Types. I tried adding one, using New... but it wouldn't 'stick'. So
then I used Open With, chose the list option, selected WMP, and check
marked 'Always use this program'. That works in the sense that d-clicking
an MP4 now opens it in WMP. But why is there still no entry for MP4 in
File Types please?

If it gets out of control, you might want to delete the MP4 association and
create a new one. But be aware that this will reset the displayed
icon/thumbnail and remove MP4 specific property tabs.

What did the registry search reveal?
My XP3 reg has about 6 significant MP4 entries
and about 20 what I would consider insignificant.

Thanks JJ, but as mentioned I did try to "create a new one".

I've always assumed that, if d-clicking a file with extension XYZ opens
that file in some program, then there will be an entry for XYZ in File
Types showing the details of this.

But as described, that's not so in this case, as you see:

Thanks Paul. Haven't yet done any registry searching for this. What target
gave you those 26 hits please?

MP4 association File Types is::
QuickTime Player

You need to uncheck mark it there.....
or QuickTime will keep resting it..

Sorry have been gone a few days.
Target was MP4.
I have several MP4 players and converters.
