I am looking to get as a gift a portable tv and dvd player combo. my question is, will the tv work better without the dvd player or does the combo work pretty well? i have seen a couple of brands(coby, awa, viore) that is a 10" portable tv, dvd player combo, has anyone had these and how well do they work? what are the best brands for this item, thanks in advance for answers and happy holidays!
