The Intel i740 was a 3D accelerator from Intel to promote the at this time new AGP bus. The on board SDRAM is for framebuffer only. For texturing the AGP bus is always used which offers half of the bandwidth compared to the on board memory. Then benchmarks showed that the PCI version performed faster in benchmarks. The cards performance is compareable with a Riva128.
Here the Video Module Interface of the i740 is used for a DVD accelerator card.

The decoder seems to have problems with the format of PAL 4:3 resolution.
If the movie is 16:9 with less vertical lines it seems to work.
Audio sounds as if capped with a low frequency.
Conversion Quality Setting in Windows was set to high though.
The daughterboard is mapped through the i740 resources.
