i have a phillips dvd player that has an hdmi output to transform regular movies into hd movies. can i also play movies that are already in hd?
No. The electronics and optics in your Philips DVD player are designed to only play DVD discs, even though they do "upscale" them to HD when playing via the HDMI output.
HD-DVD is a totally different format to DVD, even though the discs are the same size. For starters, the "pits" on an HD-DVD that store the digital information are a lot smaller than on a DVD; DVD players use a red laser to read the discs; for HD-DVD, you need a blue laser (blue light has a shorter wavelength than red light), as the wavelength of the red laser in a normal DVD player is too big to be able to resolve the tiny pits on an HD-DVD.
Secondly, even when physical considerations like that are taken into account, the format of the data on the two discs is likely to be totally different too - meaning that the electronics in your player would not be able to handle the data on an HD-DVD even if the laser in your player was able to read it.

NO
An upconverting DVD player is NOT an HD DVD player.
