Hi, I want to get a PVR for Colombia, SouthAmerica. I want to use it to record, pause live, and skip commercials. I don't mind not having a TV Guide on-line (in fact, I don't think there is one for Colombia). My TV source is SkyTV (similar to DirectTV). I am a complete newbie on PVR, but from what I have read, TiVo, ReplayTV and UltimaTV charges you with a monthly or life fee, for a service I won't be using (the guide). What are my options? Are there any PVRs completely...
