I saw these today, as well. I didn't buy any, though, since for me, the main attraction of buying original discs are special features. Yes, even more than "not stealing intellectual property" or "doing the right thing."
From the jackets, these look like counterparts of the C-Interactive titles, with one big exception: since they do not include all the special features, I think the main feature would look okay on a DVD-5. I'm just guessing that's the case... I don't know for sure if that's how these titles were encoded, since like I said... I don't think I'll ever buy one of these "budget releases" at that price.
