Bluray Iso Scanning

[fas77]

Running Sage 7 final
Windows 7

I have all my bluray iso's in a single directory.
When I select blueray from sage it lists the iso's.
I was getting errors when I tried to select one to test playback.
What is happening is when I scroll the list the iso's appear to be mounting
and unmounting in VCD.
I guess sage is trying to generate thumbnails for each movie.
The one I select won't mount until this is done.
After a few minutes sage stops trying mount the iso's and allows me to mount
the one I select.
I also noticed if I scroll down my iso list in sage it starts mounting and unmounting them again.
I can tell this is happening by looking at VCD mount history.
It will show the iso's being mounted.

Is there a way to prevent sage from scanning my iso's every time I
select Blueray from the sage menu?

Thanks

After more testing I confirmed what is happening.
For some reason thumbnails are failing to get created
for Bluray iso's.
Because there is no thumbnail, every time I go to the
Bluray folder sage tries to create thumbnails.
This causes sage to mount and unmount the iso's as I scroll
through my list.
If I stop on one Iso and wait for a few minutes sage will
finish randomly scanning iso's I passed on the list and let me
mount the one I want to.
Until sage is done scanning it is not possible to mount an iso.

Any help would be welcome.
