We now have Little Reader and Little Math and use those a lot.
When I was pregnant with my daughter we started purchasing the Little Einstien dvd's. My daughter likes them but I have stopped showing her them since I realized they aren't really teaching anything. It's unfortunate too because we own about 20!
We own several signing time video's and HIGHLY recommend them to everyone! My daughter can not get enough and for that matter neither can my 10yr old son. The video's are clear, easy to learn from and fun. My daughter asks for more signing time all the time.
We also have Your Baby Can Read and Preschool Prep meet the Sight Words.
We started with YBCR and she likes it but it doesn't seem to hold her interest long.
We just received Preschool Prep as a trial from a friend and my daughter loves them. It funny because they repeat the word about 20 times beofre they go on to the next one but she sits still and has begun repeating and reading the words already.
We are still using YBCR though and she practises the words outside the video with flashcards and LR.
