Need help in buying DVD player

[rossy19]

Hi,

I am planing to buy a DVD player for my 29inch PhilipsCTV.

The player should play avi, mpg, RM video formats.
5.1 channel support with DTS surround sound.
USB( need portable USB HDD support if any brand has)

I have found 2 model in philips which has above features except 3 or 4 features.
DVP3568
DVP3588

Please suggest if you know any others.

Thanks
Ro
