If you are looking for American English, the Leapfrog videos are very good. You may also want to try out Rock N Learn Phonics because it offers many more words than Leapfrog. I do, however, recommend previewing it from the library (or interlibrary loan) because it's presentation is not as professional as Leapfrog. Also watch for the WatchKnow reader to be completed, I'm not sure when it will be available.
