Portable DVD player recommendations?

[xhail]

Sorry, didn't quite know where to put this topic.

I want to buy a portable DVD player with the following features:

7" screen
2.5hours or more of battery power
playback of SVCDs with a CBR of 2520 burned on CD-Rs

Anything else is just icing on the cake.
I am looking to spend about 500 dollars. So any recommendations?

Thanks

An old P-500 or P-800 laptop would do it alright.
Along with all your other formats as well..
$500 should be about the cost. (Used)
