My card HD4770 has UVD2.2 chip, support is as follows:
Windows:
Generic: Never tested
Catalyst: Full Support
Linux:
OSS: Full support via VDPAU, still very buggy, tends to crash the driver sometimes. Some applications have issues with it (ex. XBMC).
Catalyst: Partial support, H264(high) and VC1 only via VAAPI.
