I've got one here but can you tell me how to 'benchmark' with the DXVA checker? All I can see are device and capabilities listing. And the C-50 definitely must have DXVA active to smoothly play 1080p materials.
Edit: Ok, I figured out how to do the benchmark. The checker, however, defaults to "AMD Fast DnD" as decoder and it crashes every time. How do I make the checker to use a different decoder?
If CCCP fails, you might need DIVX's decoder. see below for tut:

For C-50: (you may skip the MPCHC part)

if installation success you should be able to benchmark using DIVX decoder. (you may skip the )
waiting for good news
