Hiya
This is for WMP:
Go to Run and type REGEDIT
To remove the most recently used URL from Windows Media Player, use Registry Editor to delete the specific URLx entry in the RecentURLList folder under:
HKEY_CURRENT_USER\Software\Microsoft\MediaPlayer\Player
Or, delete the RecentURLList folder to remove the entire list.
To remove the most recent Radio URL from Windows Media Player, use Registry Editor to remove the Radio_Station_x entry from the MRUList folder under:
HKEY_CURRENT_USER\Software\Microsoft\MediaPlayer\Radio
Or, delete the entire MRUlist folder to remove the entire list.

Not sure about Quicktime, as I don't use it, but if you go to the Registry, and look in HKEY_CURRENT_USER\Software You should see the Quicktime folder.
Does it have an MRU folder in there?
Do exit, just click the large X.
If not, its okay, as I can ask someone with Quicktime to take a look.
