Problems reading burnt DVD's

I have a HP DVDr/rw that has no trouble burning CD’s and DVD’s…The CD’s are fine, but the DVD’s will work on anything other than the DVD drive it was originally burnt on…please help :confused:

Could be a trouble with the mediatype (-R vs. +R) and with the player (some standalones deny accepting various media) or a authoring/burning problem.
