I'm sorry if this has been asked, but is anyone running a Series 3 TiVo with a single Multistream card and able to record 2 sources? Everything I read says this doesn't work (probably explains why I can get a Series 3 cheap). Paying to rent two cards, while losing on demand financially defeats the purpose of dumping the motorola DVR. I said financially - I miss my TiVo functionally Talking FiOS here. Thanks!
