CNET have published a review of the Cast Grabber MP3 player accessory. 'The Cast Grabber promises just two things: that it will charge any USB-powered device; and that it will download podcasts to your MP3 player without the aid of a computer. In our testing, the Cast Grabber delivered on its promises with one exception--video podcasts. Unlike audio podcasts, which conform to the MP3 file standard, video podcasts come in so many varieties that very few will agree with your particular MP3 player without first being converted using computer software. Even our fifth-generation video iPod and third-generation iPod Nano, devices for which the majority of podcasts are tailored, could not playback video podcasts downloaded using the Cast Grabber. Despite our disappointment with video podcast support, the Cast Grabber proved itself consistently capable of downloading audio podcasts directly to several of our iPod and non-iPod MP3 players.'
