I am about to get a new iMac G5, and would like to get a TV tuner. I will mostly be using the TV tuner for watching TV, and not for Playstation/Xbox etc. I wanted to have the ability to record TV shows on my iMac, so a video capture feature was necessary. I've sort of come down to the Elgato EyeTV Wonder USB 2.0 or the EyeTV 200. The EyeTV 200 is firewire, and the Wonder is USB 2.0. I've looked at the specs, but does anyone know of any major performance differences between the two? I saw some others write in the forums that the EyeTV 200 has an encoder, whereas the Wonder doesn't. How would this affect watching full screen TV on my iMac? Thanks for your input!
