Surely they are excellent-looking, but they could be from another good-quality source (the Japs have a lot of them) and not from the (US) Warner management team. We all know that the versions of all not-released-on-DVD-piror-to-2014 shorts that currently air on Cartoon Network arguably come from low-quality incorrectly-tinted sources, right?

Q: Does "Horten Hatches The Egg" from the "Best Of Dr Seuss" DVD look similar to those on the JP Tweety DVDs? I still don't know...

While certainly not remastered to the standard that has been set by the later Looney Tunes Golden Collections and the Popeye discs, I'd argue that the cartoons on the I Love Tweety DVDs are remastered. Most of them look very similar to the Standard Definition transfers of post-1948 Looney Tunes found on the first Golden Collection.

By today's standards, would I consider these transfers necessarily "restored"? Eh, not entirely. I do think that most of them were sourced from 1998 "Dubbed version" copies.

Regardless, though, they are still worth getting copies of--at least for collector purposes.

They were remastered and they were restored, but they're not restored in HD. It was just your basic dirt and scratches clean up and stuff. Since "they're already done" some of those cartoons appeared this way on the Golden Collection to save a buck
