I'm having a blast encoding all these old videotapes I have, but want to make sure that the files I'm making now will still work on down the line.

They work fine in MyDVD and DVDit, but I was wondering if these settings will also work for Scenarist (when i save up the 39,000$) or for when they finally come out with a consumer authoring program that does everything I want it to (and is less than 200$!):

#I=1

Output Interval: 1 GOP
Closed GOP (MyDVD and DVDit say it needs to be closed so that's why I do)
Detect Scene Change
Stream type: MPEG-2 VBR

These create great videos for the cheap Sonic stuff, so will it also work on Scenarist or other super-professional authoring programs???!

Thanks
