Not a lot. Most of them are US boxsets, like some of the "orange box" season sets for DBZ, Outlaw Star, Gurren Lagann, and Cowboy Bebop. I've got a few scattered Yu Yu Hakusho DVDs (both R1 and R2), the first 13 episodes of the Digimon Adventure dub on DVD (barf), and a few Slayers DVDs.
I've also got the complete set of Powerpuff Girls along with its few movies, and an R3 Taiwanese release of Ojamajo Doremi #. I also used to have Motto Ojamajo Doremi, but I gave it to a friend as a gift.
I'd love to get all of Ojamajo on DVD but it would cost me something like $4000 to get everything since it's rare, out of print, and Japanese DVDs are always overpriced. The BDs of season 1 are coming out in a month but that alone is several hundred dollars for a shitty upscale with broken colors like Digimon Adventure.
Oh yeah, I've also got Hong Kong, region-free pirated DVDs of the complete set of Yu Yu Hakusho and Cardcaptor Sakura. The YYH subtitles are Duwang as fuck, while CCS is passable. But I loaned CCS to a friend whom I haven't seen since high school.
This is why I'm glad torrents and IRC exist. DVDs are too expensive unless they happen to see a US release. I can justify $30 for a 50 episode show, but not $550.
