Yeah, IYH 2, and this show were only available through WWF Magazine, while IYH 4, 5, Good Friends Better Enemies, It's Time, A Cold Day in Hell, and Degeneration-X were never released at all, or at least in the case of IYH 4, and 5 were edited together on one two hour tape.
Actually, GFBE was released on Coliseum Video, but like Mind Games it's pretty rare and used to sell for a lot on Ebay. The cover had some generic name for the tape that wasn't the PPV name (like all the IYH's did back then), and had a shot of HBK with Diesel's face in an insert.
If we're talking about Silver Vision, then everything was released. I actually have both It's Time and ACDiH, both of which are actual NTSC copies. I also have IYH 4, a full version of One Night Only, and D-X, but they are converted from PAL. IYH 5 also was released on its own, again only in PAL, I believe.
GFBE In your House was called "Mega Matches '96" by coliseum home video. I've got it actually and outside of the main event its a dreadful show. But that main event was kick ass, especially for 1996 WWF.
