Thank you very much for the information
I see a lot of mixed reviews for all those $50-200 PAL to NTSC converter devices up for sale online. Also for the prices the iScan HD is going for perhaps I should consider an Edge.
I use my TV mainly for gaming but of course I watch a fair share of films as well (a large amount of animation included, which I hear can have odd cadences that the Edge could quickly pick up on).
My set has a 2-frame delay even in its Game Mode or PC Mode, sadly. I'm not very sensitive to input lag so I don't notice it (I play online FPS games fairly often); on the other hand I play a LOT of 480i/576i PS2 games and would love a device that can process that decently, however it would seem without Edge's Gamemode enabled I would get a total of 5 frames of delay which I'm almost certain I'll notice and get bothered by
Another use I could see for the Edge is its Zoom function. One to get rid of the black bars in film with aspects greater than 1.78, and Two to fix the letterboxed state and improper aspect ratio that my PSP displays with its Video Output mode. I bought a PSP->VGA converter that allowed full-screen output of PSP games, but unfortunately I couldn't stand the red push and got rid of it.
I read that you use the XRGB-3 to zoom in your PSP, Fudoh. Ringing aside, do you think the Edge can offer similar performance? Because (yet another) thing I've read on the Edge is that its scaling quality during Zoom is pretty solid.
And then there's PS1 games. They get a large amount of use time, too. I already have a Playstation 3 though, which is considered to have pretty much perfect 480p rendering of 240p titles. Not sure if the Edge could offer any major improvements in this department.
The Edge might help a tiny bit with scaling 720p PS3 titles to 1080p, though. Then again with HDTVs being made mostly for HD resolutions, their internal scalers may already be quite optimized for 720->1080 scaling (I have a higher-end Samsung model from 2009, dunno if being a top model means they focus more on the de-interlacing/scaling chips or not).
