It's best to do what gives you the result you desire. Try some short sections both ways and see what happens. My personal preference would be to have a global setting to always disable resampling in all cases, without exception. Some folks prefer the blurring of frames to the jerkiness of mismatched cadence. I don't.
I'm with Kelly on this one. Seems like there ought to be a global setting to disable resampling. In the meantime, this script helps me: SetResample.zip
