With normal power you have decoupling on the chip? It does sound like they are out of spec (are they genuine parts or clones? Were they soldered for too long causing thermal stress perhaps?)(Also double check your caclulations - print the raw temperature value and do the conversion by hand to check)
Maybe there should be "post the code" reminder?And a good question is -- are you using the Dallas One-Wire code found here or where is it from?The Dallas Library from here works...http://milesburton.com/index.php/Arduino#Libraries
