processor choice

[supernoob]

Have this motherboard laying around MSI KM4AM-V Via VT8237 and I like to use it for a dedicated sage box. what processor would you recommend? I'm looking at:

AMD Sempron 2400+ 1.667GHz

Or

AMD Mobile Athlon XP 2400+, 266FSB, 512K Cache, 45 Watt (newegg sez 266 but I beleive its a 333fsb.

which is the better choice for this board? I'm not really going to be trying to overclock it, I just want something fast enough to function as a family room computer/sagebox. Will also be running this off of a 250watt PSU.

I'm new to this also, but want to offer up a warning. I currently have a AMD XP 2000+ from my son's old computer. This process is plenty adequate to run SageTV with the Hauppauge PVR 250 (it has an onboard encoder so it doesn't load your CPU at all). The processor only was running @ 20-30% during playback.

The warning is if you want to start using Ffdshow to try and improve picture quality (it works really well with DVD's) then this processor isn't enough. I just ordered the XP 3000+ and this may just be enough for what I want to do (if not I have to live with it, because I'm not going to buy another motherboard).

So the warning is that if you get caught by the tweaking bug and want to continually work on the picture quality, then you should probably bit the bullet now and get a big processor. Otherwise my experience is that the 2400 would be plenty adequate, as the 2000 works fine for me.
