The result is extremely flexible TV out. Finally, someone has gotten a convergence part right. The only downside is that you can't hook up a second PC monitor - but then, you probably won't want to with this card. For example, you can set it up so either the TV screen, the PC-VCR remote, or both are always on top, which makes TV viewing a little easier. When I used the autoscanning feature to set up my cable TV channels, the G400's tuner found all the good channels correctly, unlike 3dfx's Visual Reality software.
Image quality is superb, even when scaled up.
We attached a Sony Digital 8 camcorder and a Panasonic BT-S1360Y studio monitor for testing capture and output. The Marvel G400 uses a Zoran M-JPEG chip for hardware acceleration of the compression process. The Marvel's capture quality is more than good enough for S-video. You take care of all your editing, then convert it to MPEG-2 if you need it. Overall, the Marvel G400 is one of the most polished products of its type I've seen.
