Paul,
I would suggest the Geforce 2MX (the Hercules one) and these are great cards for DVD. I also have read excellent reports of the Radeon but specific Timing Resolutions are difficult on this card though you don't appear to want this feature.
Therefore the choice really comes down to budget. Personally running at 800x600 my Geforce 2MX's run games really well with all graphics options switched on. Quake 3 looks awesome for example. The higher spec 64MB card comes into its own at the much higher resolutions.
Personally I use a Geforce 2 64MB Ultra in my main machine, Geforce 2MX in the Lan Machine, Geforce 2 MX in the HTPC and an old TNT2 32MB in the Kid machine.
