The ATI Mach64 series was a long available series of 2D Windows Accelerators by ATI with 64 bit memory bus. The GT along with the VT introduced 3D acceleration features and support for various video memory types. The Rage II+DVD added acceleration functions for DVD playback (Motion Compensation) that are used by the ATI DVD player.
The Rage II has ATI CIF support (ATIs own proprietary 3D rendering API).

ATi Rage II+DVD DVD playback review (brief scene footage from The Fifth Element DVD):
My notes:
System used:
P2 233 MHz on i440LX chipset.
Ati RageII+DVD PCI 4 MB EDO 60 MHz, SB16
graphics mode 1024x768x24 Bit
Ati DVD Player 3.2.0.1
I used the same driver package as for the Rage 128 from ATI driver CD 6.01.
DVD Menu worked, no problems with PAL resolutions as with the other ATIs.
I had to lower the color depth to 24 bit at least, since it stutters at 32 bits.
This seems to be a bug as it appears also with faster CPU clocking.
The quality is average, no postprocessing at all, you can nearly see the decoded pixels.
Note also f.e. the red line when the starship is first shown.
After seeking it needs some seconds until audio and video is in sync again.
Overall it seems already very CPU limited at 233 MHz.
Something else I noticed is that in 16 and 32 bit color depth 2D-GUI acceleration works, but not in 24 bit, as you see
when I move the window.

ATi Rage2 performing ATI Dawn Benchmark that was released for ATI Rage 128, be aware that ATI Rage 128 is at least two generations newer. Thus the Rage 2 is actually way too weak for this (Rage2C with 4 MB EDO DRAM):
