Brainy Baby - ABC's . Believe it!... This is a great video. Brainy Baby just seems to really know how to connect with children when it comes to teaching. The lady who gave this a one star and wrote a book about her feelings, is a bit over the top and has way too much time on her hands. We also homeschool our children and found that this video really helped them when they were younger to learn the alphabet. Remember, this is a PRESCHOOL video! Your children are being introduced to learning situations, not studying for a college exam! We have found that all the Brainy Baby videos are top quality and do an excellent job of teaching. Our boys knew the entire upper /lower case and all the letter sounds around 16-18 months! It was amazing and I KNOW that these videos played a big part in that. I am also impressed that all of their videos have a very specific educational outline that all my teacher friends say is excellent for teaching preschoolers. After doing a little research, I found a little known fact that it was Brainy Baby that created the first set of "infant-preschool" videos over 10 years ago (way before the Einstein series). So, that really gave me confidence that the producers at Brainy Baby really had the experience and track record. My advice, I don't see how you could go wrong for a mere $15 investment in your child's future. I own all of them and wish Brainy Baby would make more!

Not recommended . My husband and I were very disappointed with this DVD set. One DVD contains an "action documentary" with music - we did not like that DVD. We thought the second instructional DVD is mediocre and might be helpful if you are a complete novice. The treatment of subjects is in our opinion pretty superficial overall. There is little breakdown of technique. There is minimal race footage, which is helpful to watch to learn by watching experts. Parts of the footage seemed recycled - we heard very similar discussions about ski wax in the separate "tuning" and "equipment primer" sections. You cannot watch the DVDs straight through as they dump you back into a main menu after you complete a scene. So you must frequently fiddle with the controls to select scenes to watch. That feature is helpful if you want to access scenes easily perhaps but we did not like it. I am not usually a complainer but we were so disappointed with this set that I wanted to put up a review.

Great film, lousy DVD . I'm really tired of the shoddy DVD manufacturing used by many studios and distributors. This is a great film. I have it on tape. I was thrilled to see it'd been released on DVD. I love Italian knock-offs of American films (STREET LAW seems inspired by DEATH WISH), and I'm a Barbara Bach fan. So I bought this STREET LAW DVD brand new, as soon as Amazon offered it, without waiting for the price to go down. I unwrap the pristine-looking DVDm pop it into the player, and after a few minutes it pauses. Then it pauses again. It pauses constantly throughout the film. I mean at least once a minute, often several times a minute. Pause, pause, pause. Most of the pauses are brief, some last several seconds. I eventually took out the DVD, cleaned it, but it didn't help. I suffered through 50 minutes of this film, then gave up. VHS was a decent format. Tape had problems, but nowhere near as bad as DVD, with all the skipping and scratching. (And Google "DVD rot" -- see what comes up.) Still, changing formats is a great way for studios to resell us movies we'd already bought, so I guess it makes sense for them. I don't know whether I got a bad copy of STREET LAW, or if this DVD is part of a bad batch, or how widespread the problem is. But beware
