I want to record from tv/video etc. what exactly do I need to do this? What kind of hardware/software? I Appreciate all kinds of help.
The most affordable option for a TiVo-like device is called EyeTV by elgato - http://www.elgato.com/. Formac makes more robust (but significantly more expensive) solutions - http://www.formac.com/p_bin/?cid=solutions_converters.
... Too bad I have built in AV in and out ports but OS X dosen't support it! DAM THEM DAM THEM ALL TO.... wait... where am I??? (I herd EyeTV was good, you should get it)
