I have been taking that approach, and I have eliminated a few things. First of all, it's not the signal, or my splitters. My computers can show DVDs just fine (don't have Blu-Ray yet), so assume it's not the graphics. So, at this point I'm assuming it's the router. Our Linksys router is rated at 54 Mbps. From what I've been reading, streaming HD video (especially fast forwarding and rewinding) requires a router that can handle 300 Mbps. So, I think I'll be ordering a new router. Even if it doesn't completely solve the problem, it will certainly speed up our web browsing.
