[vdr] Advice

[YUP]

Hi all,

I need an advice.
Actually I'm looking for usb H.264 or mpeg4 encoder which can work with 
VDR, I need it for watching hdtv and stream video in mpeg4 or h.264 on 
my dell GX1 (http://support.dell.com/support/edocs/systems/ban_gx1/ , 
pentium 3 with 256 RAM, 600 Mhz). Encoding with mencoder gives bad 
results, processor is too slow for it. I found the following usb encoder

So, can I use it with VDR? If positive, then how? Can it replace my 
Hollywood Plus? Or can it work together?
