This was a useful bit of kit I bought years ago – a DVD player with an ethernet port at the back (it even came with a free wireless adapter). Basically, you plug it all in, install some software onto your PC and you can stream DivX, mpgs, etc from your PC.
Only thing is that if you lose the software for it you can’t stream shit. I normally chuck installation CDs as soon as I’ve double checked they’re available on the manufacturers’ website but in this case I hunted high and low after losing the disc and couldn’t find it anywhere on the web.
After a good year or so it turned up, so I’ve stuck it on my website to share the love. 33mb download here: http://www.markbrewster.com/downloads/lmspc-v141.exe
