Sure, it's costly, but I believe the standard is 15, and common practice
is 12. 30 may work on most players, but it's out of spec. I wouldn't
suggest authoring a DVD using keyint=60 just because it happens to work
fine on the player you own.

There's some threshold where you decide that a proper compliant DVD
isn't efficient enough for your needs, and you consider the fact that the
so-called DivX players are now going for under $50. They're guaranteed
to work fine with long GOPs. Why violate the DVD spec when you can just
move past it?
