Looks like the right one. You'll use the primary battery for the first movie, and that for the second.
Using headphones will save some juice. It'* possible you'd get 3 movies out of the 2 batteries.
That player has all the same features as mine. MP3, CDR, JPG picture CD, etc. And the music mode lasts much longer, because you have the case closed and it'* not running the LCD screen.
That unit comes with both chargers, and all the cables, too. Looks like a great deal. The only thing I don't see is a remote. My Audiovox came with one.
