Hi everyone - my first post

Just got my mini yesterday - my first iPod - and still learning the ropes.

I have uploaded about 20 albums to iTunes and synced with the iPod.

When I select some of the albums to play on the iPod from the menu, rather than starting to play Track 1, it quickly skips through all the tracks without playing them and then returns to the menu.

The only way to hear the music from those albums is to press pause whilst it is skipping thru the tracks, return to Track 1 using the Rewind button and then release the pause.

Does anyone know why this might be happening?

A may be able to offer a clue - all the albums that were affected were ones which I had coverted to mp3 using RealPlayer (because it converts at much greater speed) and then added to my iTunes library, using File, Add Folder to Library. The folders were not however in my iTunes sub-directory on my laptop. Does this make a difference?

I would be grateful for any suggestions as to why this is happening and how I can prevent it.

Thanks
