Abgx360 screenshot of ssv2

I really tried to Google it, but seems to not have a consent from the community. I never paid attention to this particular thing, burned a lot of games and worked just fine, even using a notebook non-modded dual-layer burner. But now I discovered this and I'm not sure of what it really implies in the real world.
My doubts are:

1. What's the differences between SSv1 and SSv2?
2. What burning a game, on a LT 3.0 xbox 360, with SSv1 or SSv2 really implies?
3. Is there a new way to check the DMI and SS filenames, as long as abgx360.net/verified.php is offline? Like, hadzz website has like 15k stealth files, but I dunno which one to use with each game (to change from SSv1 to SSv2).

Thanks in advance.
EDIT:

1. Use hadzz46's website VERIFIED LIST(WIP) to see if your game have SSv2.
2. If so, convert SSv1 to SSv2 using IronRingX's TUTORIAL.
3. Never trust Windows search, always use the full SS/DMI file name in the search bar.

Thanks again for the help, you're awesome.
