It is hard to trouble shoot without some code to look at, seriously.

The implementation of media in v3.5 is essentially the same as in v3.1
but it has a few extra options that produce smoother media and offers
a little better control. However, you should be able to take what you
learn in v3.1 and apply it to v3.5 without suffering too much permanent
brain damage.

Yes you can run both version if you install them in different locations
on your hard drive. If you install v3.5 over v3.1 then you lose :~)
