d_j and Y_T,
As good as the V3 DVDs were, I would love to see V4s. FWIW, I've been seeding the V3 DVDs since day one, and I think I've upped 30 full copies of the ISOs. I'll be happy to do the same with the V4s.
It's a shame that the Bluray versions won't work for me though. Even though I have a 65" 1080i TV, Bluray players refuse to trust it because of HDCP, and won't provide full-rate video. Bluray is evil... So if better DVDs are an option, I'll gladly support them!
