I wouldnt go for the ati 2400pro as it struggles with 1080i. I believe there is either a driver or hardware issue, but its not known if it will be fixed or not. Best not to risk it.
Have a read of this:

The ati 2600xt comes highly recommended. In saying that, then 2600Pro is also a nice piece of kit. It is very similar to the 2600XT. Some people have reported that the 2400 series of video cards offer poorer image quality than the 2600 series.
Another thing is that if you plan to download HD material (encoded in x264), then your video card will not decode it. It will be totally CPU dependent. IMO, get a strong CPU, this way you cover all your bases. Cost may prohibit this, but you might be able to pick up an Intel C2D E21x0 CPU, 2nd hand, on the cheap.
