Dunno about LE and VE (though it seems VE is the equivalent of the GF2MX - a stripped down version) - but VIVO stands for Video In Video Out - great for watching DVD's on a TV and capturing video from a vcr or something.
I've been doing some looking into the Radeon card, and the more looking I do the more 'versions' I find. From what I can find at Creative's site, there are three base modles (of the 32 MB card):
1. Radeon VE #100-430119: Dual display model (standard CRT and flat panel outputs)
2. Radeon #100-430029: Standard base model. One output connector for CRT.
3. All in Wonder Radeon #100-709004: Dual display output, TV tuner, VIVO (video in video out)
I did not see a listing for the Radeon LE at their site.
Now the fun part starts ;D and it starts looking like a Chineese menu....
(not all options avaliable with all modles)
a. OEM or Box
b. 32 MB DDR or 32 MB SDR
c. PCI or AGP
d. With or without VIVO
