[QUOTE="mm1352000, post: 888683, member: 82144"] Hello again :S Not at all. This is true for WMC, but not for MP. With MP you should be able to timeshift/record all the channels from one frequency (AKA "physical/RF channel") with one tuner. This is possible because physically speaking, the limitation is that each tuner chip can only tune to one frequency at a time. However there is no reason why all the channels that frequency/RF channel cannot be received at the same time. Please do try it. So I wonder if that internal signal splitter is a factor. If the frequencies were wrong, but close enough to barely get lock then this could happen. For example I'm checking the frequencies for Cox Cable, Tuscon in the Silicondust channel DB ([URL='http://www.silicondust.com/hdhomerun/lineup_web/US:85706#lineup_8347283']link[/URL]) and the frequencies seem quite different. That could be because I'm looking for the wrong postcode or because the frequencies have changed recently and not been updated in the SD Db. Since you know your own post code, perhaps you could check: [url]http://www.silicondust.com/support/channels/[/url] So to be clear: no real time scanners (virus protection, search indexing etc.)?
