[maemo-developers] Video decode capability of N810

[From: skelso at nc.rr.com]

At the risk of being wrong, I'll sum-up what I think I've heard here over the years and hope others will correct/clarify:  The OMAP in-built video support doesn't go up to the 800x480 resolution of the Internet Tablets.  Therefore, Nokia used external graphics chips from Epson.  The 770's chip works up to it's design bandwidth for video.  The N8xx chip has a bug causing tearing at design bandwidth, so its video resolution and/or frame rate must be artificially limited.
