PC Windows 7 Home OS, Phone connects to PC media folder without any issues, media plays (dependant on connection) via WiFi.

Problem that I am seeing is that media files that were present on the PC meida folder are still appearing on the HTC connected Media of my Video app.

Replication sets

Place a media file on PC in Libraries/Video
Phone, Open Videos app
Go to Connected Media section
(WiFI connection established)
View media in the list and play the video from the PC.

Rename the media file = no change to phone listed media.
Move the media file = no change to phone listed media.
Delete the media file = no change to phone listed media.

in all three cases the file not only appears when the phone is in WiFi range (if not in range it appears with a connection error for WiFi out of range) but the file can be played, despite it no longer being on the PC?

Please advise how I clear my media files listed on the Connected Media tab.
