Yes.  The frontend is to be used for playback.  If you wish to play any 
content other than what VDPAU offers support for, you need CPU power.  
That means codecs not supported, codec options not supported, and even 
some data corruption from a bad recording that ffmpeg can push through 
but VDPAU chokes on.  If you want to do flash video, which still does 
not provide hardware accelerated scaling and colorspace merging, you 
need CPU power.  Having a worthwhile CPU offers the flexibility to do 
something you may not have initially planned for, without having to buy 
all new hardware.

Foxconn MiniITX H67 board            $55
Intel Celeron G530                            $57
2x2GB Mushkin DDR3 1333             $26
Rosewill MCEUSB remote                $25
M350 Case (VESA compatible)        $40
PicoPSU-120 + 102W adapter         $60
                                     Total                $263

The cheapest ION barebones on Newegg is is $240, but then you have to 
add memory and infrared.  You can find ION motherboards for $153, but 
then you have to tack on a case, and power supply, and memory, and IR, 
putting you right back up there with that Celeron system.
