Is there any difference between these sentences:
You must try it.
You should try it.
With some respect, I mean when talking to elders.

Well, in general, 'must' carries more strength and obligation than 'should'. When speaking to elders, or to persons in authority, 'should' is more polite.
If you are speaking to an elder with whom you are familiar and usually speak with casually, 'must' is okay, but tone of voice is important. It's difficult to illustrate via text, but your tone should sound more imploring and excited than commanding or insistent.
