I could swear I remember doing chroma-key with it... Just reversing the disolves. Hell, it's been 12 years since I've messed with it, I could be mistaken... Or maybe it wasn't an SGSX. *shrug*
Really, I'm just planning on using it as a monitor replacement. My Pinnacle AV/DV does everything I need it to... Namely analog capture, since I use an S-VHS camera. Just need to get a MUCH bigger harddrive soon.
