My search on the forums yields nothing. Surely this isn't uncommon? Win7 HP RTM No configuration changes, they just all disappear, still see the one MKV I have. Quite annoying.

It appears I can see the files when in "DATE TAKEN" viewing mode. Cannot see in FOLDER view. The idea to test this was found here: http://social.technet.microsoft.com/Forums/en/w7itpromedia/thread/170892e4-b206-45e9-ad1f-e903b87a3efe The mystery remains.
