I have had TiVo for years and just yesterday I finally set up my Tivo to my wireless network and downloaded some TV programs. When Windows Media Player(v.10) tries to play them, I get an error message. I assume I need these aforemementioned codecs, but when I go to their sites to download them, they want $14.95!!! Does this mean just to play a TiVo video I have to cough up 15 bucks? The Windows Player works fine with emailed files normally. I have a lot to learn about this networked stuff now, so I need some help.
