Yes... But what I was really after was to do the same thing for the OSD data. The amount of OSD data is a lot less then for the video, and you could make assumptions (like 10x) for the time it will take to transfer it, and it still wouldn't be a problem.
But, as far as I know, this hasn't been tested, and I don't know if it's possible (depends on the internal method dxr3 uses to create the osd).

Maybe the databook for the em8400 can shed some light on it? It should be just an advanced version of the em8300. See

I seriously doubt that dxr3 driver developers are unaware of this. According to this datasheet the em8400 is capable of a full 256 colors OSD. Btw: http://sourceforge.net/mailarchive/message.php?msg_id=9640995 no follow-ups.

Probably. I also dont understand why no dxr3 developer have tried to tackle the x-card. They have the dxr3 to build on, there's more documentation available, and there's even a binary linux driver which could be tried to reverse engineer.
