If your DVD player reads JPEG'S then just copy them to the disk and play them, alot of new players do support jpeg's but yours may not.
They are not expensive to buy but make sure if u do purchase one that it will do what u want.
Otherwise if your graphics card has tv output just hook ya tv up as a monitor.
I use my tv as a monitor (great for games on 32" wide screen).
To check look next to the monitor output on the back of your pc, if theres a small s-video port then u can do it this way!
