Hi Jason:

I found in the ATI website about a new graphics embedded solution, ATI Radeon E2400. They claim they are shipping parts since january. It comes in two flavors.

The ATI Radeon E2400 Discrete GPU has a compact 31mm x 31mm package design, with 128MB of on-package GDDR3 memory. This product is ideal for space constrained designs helps eliminate the need for potentially complicated on-PCB memory layout.
The ATI Radeon E2400 MXM-II module has 256MB of GDDR3 memory and is based on the open standard MXM-II module specifications, which is ideal for low profile, space constrained environments, while providing the flexibility for an upgrade path.


Maybe a solution like this can work as an upgrade to the SI2K DVR graphics, and bring more display output options.
