Here it is -- the last ActiveTV release...http://www.themediamall.com/dlink/install

Also -- If you are one of the select few who have version 1.04.xx of the D-Link MediaLounge software, you will need to manually upgrade your firmware -- this is because for whatever reason, D-Link doesn't recognize this as an older version (even though we are on .06 now). How do you know what version you have? On your 520, click the setup button on the Remote Control, then scroll down to version and enter.  If it says 1.04.xx or less, you will need to manually upgrade (the auto search won't upgrade you). To manually upgrade, put these 2 files on a usb key and plug the usb key into the front of your DSM 520 -- it will auto-detect and upgrade. This is not an ActiveTV upgrade, but gets you back on D-Link's official upgrade path so that you will get all future upgrades automatically (including the ActiveTV one posted above, which will be released by D-Link in the coming weeks).

Enjoy!
