1080p is pretty hard for most things to play.
you need to know what codec the recorder is using, odds are its a 264 style.
most of the software decoders for that are single threaded but the 
design of the codec was such that it can multithread the decoding 
efficiently, so if the machines are dual core you might be able to do it 
that way.
Alternatly you can use a graphics card to do the decoding, under linux 
any nvidia card after an 8800 (might be 8400) supports offloading most 
of the decoding to the card, I'm unsure if nvidias windows drivers 
support this for free, They used to have "purevideo" for doing that kind 
of thing but they charged a fee for the software.
