I posted about an issue Media Center has of double-queuing songs from the Explorer extension about 1-2 months ago and the issue is still here.  I'm currently using 11.0.309 but I read the changelog for the last 3 versions and this hasn't been addressed there either.

To reproduce:
Open Windows Explorer, have folder tree view active, navigate to a directory containing mp3's, right-click that directory in the tree -> Media Center -> Play.  If there's 10 songs in that directory you will have in your Playing Now: 1,2,3,4,5,6,7,8,9,10,1,2,3,4,5,6,7,8,9,10.

Specs:
P4 3.4 w/HT
2GB RAM
Massive disk space.

I can't duplicate this.

What do you mean by "have folder tree view active"?  In IE?

[JimH]

Thanks, Marko.  I still can't duplicate the problem.

Yes, marko described the setup perfectly with the explorer side-bar thing.  That's what I meant.  Just now I opened MC, deleted the Playing Now list and closed it.  Then right-clicked a directory containing mp3's -> Media Center -> Play.  It double-queued them.  So no, appending the imported songs to an existing Playing Now list isn't what's causing this.  This is reproduceable every time for me.  Perhaps the Hyper Threading feature of the cpu is doubly executing the shell import function?

[JimH]

Doubtful.  Is it possible you actually have duplicates in the directory?  Or in a sub-directory under it?

If not, please try an uninstall, reboot, reinstall.

Just did 2 more tests:

1. Right-click a folder containing mp3's -> Media Center -> Play.  There's 3 songs in this dir and each  shows up twice in Playing Now.  Close MC, right-click same directory -> Media Center -> Play.  It looks same as before, the 3 songs show up twice each in Playing Now.  No appending.

2. Right-click a folder containing mp3's -> Media Center -> Play.  The 3 songs show up twice each.  Don't close MC.  Right-click the same folder containing mp3's again -> Media Center -> Play.  Now those 3 songs show up 4 times each, for a total of 12 songs in Playing Now.  So if you don't close MC yes it appends, but it's still double-queuing the songs (at least here it is).

This problem has existed for me for quite a few months.  It's spanned MC reinstalls and upgrades as well as OS formats and reinstalls. 

Edit: And no, no mp3's in any subdirs exist.
Edit 2: Come to think of it, this problem has existed for me across different pc's.  Just upgraded my system a couple months ago and I remember it doing it on the old system (that cpu had HT as well).

Do you wear bi-focals?

Just kidding.

If the Hyperthreading is the factor, then the bug is in the OS.  But it's unlikely.

Did you try the uninstall I suggested?

Try the MC options for general/behavior also.

Check the OS file associations.  Try deleting it for MP3 and letting MC add it.

I can't reporduce this either...well not completely true...I remember it doing it when I had a playlist of the songs in the same folder but I'm guessing thats not why this is happening

yes it will add dups if a play list of the files is in the folder (just tested that).

i don't think that is a bug however

[arsenal]

AHA!  It was the playlist doing it.  I moved that out of the dir that had those 3 .mp3's and now.....no double-queing.    So any time you play songs through the Explorer extension and there's a playlist file in the same dir as some .mp3 files, MC will load both the physical .mp3's as well as the songs that the playlist refers to.  Most likely the playlist file will be pointing to the same .mp3's as are in that folder with it so you end up with dupes..

Thanks for helping to figure out what was causing this guys.  I'm curious if it would benefit everyone to either not load playlist files through the shell extension at the same time while loading audio files that way, or load playlist files as well as audio files but do some type of check to ensure there's no dupes. 

Now that I know what's causing the dupes I can work around it but it means actually going into the dir and searching for the playlist file to double-click on (which would be a little bit less convenient).   

[arsenal]

Hehe.. so did anyone have any feedback about my suggestion of not loading playlists through the shell extension?  I'd really prefer to not have to go into the dir and hunt for the playlist file..  But maybe someone else finds it useful to double-queue the songs ?

[hit_ny]

Doubtful if will happen. It just might be quicker to change your behavior.

Instead of queuing up from the folder why don't you use the right pane and add the playlist instead.

Or, use the panes and select the album from there. I have hardly needed to use explorer at all for finding stuff. Except for moving directories..but that that's another topic.
