Hi

I am looking for a good DVD player to go with my new plasma screen, an LG 42PC1RR.
I used to have a Sigmatek XM 400 Pro but it got stolen (along with my first 42PC1RR of course) mid August...

Since I have to replace the DVD player and I have HDMI on the plasma I am now looking for the DVD player that fits !

I hesitate between a brand player or a "mulitfunction" one, ie :

a Sigmatek DVBX 300 Pro that also does digital TV receiver, USB hub, ...

a brand one like the Pioneer 696, Philips DVP 5960 or Samsung DVD HD945

Few things though :

I have a small collection of music on DVD-R that is 5.1 DD and DTS but in .wav format
The "old" Philips DVD 737 player would read them all flawlessly, but to my surprise the Sigmatek XM 400 Pro did not even "see" those files...
Any ideas of what I should look for in the various players on offer to see if they are OK for this ?

I also wonder about the upscaling capabilities of some players, is it useful ?
If yes do I have to go with one that also has DCDI or not at all since my plasma has it ?

Thanks in advance for your help and comments.
