my inpoint frames and outpoint frames work in a slightly funky manner- which is probably the source of this confusion too.

I allow illegal inpoints and outpoints to do something.

For example in a 100 frame movie---

if you set the inpoint to 300 and the outpoint to 400 -- something will loop -- even though the inpoint and outpoint value are beyond the end of the loop.

in a 100 frame movie--
frame 0 can be accessed at inpoint value 100, 200, 300, 400, 500..... all the way up.

this has caused a lot of people confusion.
my reasoning was - to always make something happen....whatever the settings.
