NoOnions, I guess you've never seen a TiVo PVR then?
Even my 8+ year old UK Series 1 TiVo p1sses all over Sky+/SkyHD (I have the latter so can speak from experience). The Sky PVR interface is horrid: slow, clunky, not very intuitive, lacking in features other better PVRs have had for years and the SkyHD box crashes far to often - it's only ignorance that allows Sky to get away with it. And Sky Series Links are a joke, seriously they make me laugh when I think how poorly they've been implemented and they get deleted whenever a series is no longer showing, how dumb is that? When the new series/season of the programme is shown you don't record it because your series link was deleted months before, haha! Ah TiVo, thank you for doing it so right all that time ago!
I can't stand using the SkyHD interface, 30x FF is no different to 12x FF and it's like wading through treacle whenever I want to skip an advert. I know have my TiVo record everything, and whenever an HD programme is to be recorded it tells the SkyHD box to record it as well, so the only time I have to go near the SkyHD UI is when I want to watch the HD recorded content. It's the best compromise until TiVo return to the UK, but with Murdoch illegally restricting access to the CAM it's unlikely TiVo will offer Sky Digital support. :(
Sorry for the Sky vs. TiVo rant but seriously, it's time people in this country realised they're being peddled utter sh1te by Murdoch while at the same time he illegally restricts entry to the Sky TV market from better products than his own, which could conceivably include a PS3 with dual Sky tuners and Sky CAM.
