The set, released by our old friends Mill Creek, contains four dual-layer single-sided DVDs with five titles on each one. Disc four also contains several trailers for Hitchcock's films, including Psycho, Vertigo, and The Birds, among others. The set contains several silent films as well as two episodes of Alfred Hitchcock Presents. These discs come packed in a double alpha case.
I've previewed the films, and most of the transfers are at least watchable, with a few fairly nice ones that are below studio quality, but above typical public domain DVD fare. The only unwatchable one, in my opinion, was Secret Agent...at least I think that was it. The image had a shaky effect like a videotape with bad tracking, which is what I imagine the source to be.
More info on this set can be found here. It doesn't list the two episodes of AHP separately - it lists them as just AHP, so there's only 19 listings on there. The two included episodes are The Chaney Vase and The Sorcerer's Apprentice.
