    Whether de-interlacing is hard to achieve or not, an LCD screen must do this in order to display an interlaced source. In other words, when you feed your TV 1080i, it must de-interlace in order to display that signal on your 1080p panel.

    So the only question is whether your TV or your TiVo convert from other resolutions to 1080p better. In the three setups I currently have running on different models of TV that are all 1080p, I can see no visual improvement by running native and letting the TV convert the signal on its own vs. setting the TiVo to 1080i and letting the TV de-interlace that to 1080p. On other equipment this may not be the case. But if you can't tell the difference, then why go through the pain of having the screen constantly blank out when it switches resolutions?

    My TV switches resolutions rather quickly

    That is because over the years, resolution switching has improved in each generation of hdtvs. My latest LG switches really fast as well but my old Samsung takes ages.

    Of course when cable signal is 1080i, then fixed 1080i is the same as native, and TV must do deinterlacing. My point was that if the cable signal was 720p, and Tivo just pass it on (which happens when you run native) then your TV does not need to do the deinterlacing, but if you make Tivo convert 720p to 1080i, it does, and needlessly so.
    Now if you can not see the difference, of course it makes sense to run fixed 1080i. But some of us can see the difference.

    When the cable signal is 720p and you run native, your TV needs to upconvert to 1080p. There's always going to be conversion of the signal somewhere, unless you have 1080p content.

    Yes, but
    1) Native: 720p -> 1080p is one upconvert.
    2) Fixed 1080i: 720p ->1080i -> 1080p is upconvert + interlacing + deinterlacing.

    2) is much more work (and probably more complex work) than 1), and is noticeable for some people/video setups. That's all I'm saying.

    I hope I'll see it on my Premiere XL soon. Getting descriptive audio on the local ABC channel is disappointing.

    I have the same problem. I also opened a ticket with support.

    CRTs (remember them?) could actually output various resolutions and frame rates. Just aim that electron beam at the screen let it go. But flat screens (LCD, Plasma) have a fixed layout of physical pixel elements that are scanned at a hardware-determined rate. So if you have content coming in at a particular resolution and frame rate, then the conversion to the physical requirements of the display will be done somewhere. This can be your TiVo, an A/V box, or the TV itself.

    Is this the channel logo at the top of the guide (for the channel that is tuned)? Or are there supposed to be channel logos to the left of each channel number on the grid guide? (I don't use the TiVo guide)...

    I just got a Premiere, so I don't know what it "used" to look like...

    Yes. Except, it's even more complicated than that... because, if you look closely at a color CRT screen, it's still made up of pixels -- tiny clusters of red, green and blue dots. It's just that, rather than addressing those dots individually in a digital fashion, the TV lights them up using its electron gun, analog-style.

    Only with a monochrome CRT do you truly get a pixel-less experience.

    (BTW, "pixel" = picture element, so "pixel element" is redundant.)

    Unless you bought a good TV like a Sony Trinitron that used red green and blue bars laid out side by side, rather than the crummy dot clusters on some POS like a Zenith.

    Trinitrons still have a fixed horizontal resolution (just not a vertical one).

    Those are just rectangular dots.

    Not quite everyone. I still don't have it, even after a forced connection this morning. And before anyone asks, no pending restart either...

    Our XL2 (which at this point is only connected to network every 10 days to get updates) got the update several days ago, while the XL4 which is constantly connected has not gotten the update in spite of at least 10 soft resets from the Help menu and 3x power pulling sessions.

    Is the bug where if I'm watching a live show and decide to hit record that it will skip to the start of the buffer as soon as the current live recording stops known by TiVo or should I contact them about this? Is this the same problem listed as number 121204015104 by sea7kenp?

    Ever since the update, my Season Pass for Seinfeld hasn't been recording all of the episodes. I have it set to All and Reruns. Under Conflicts, it lists none. The episodes haven't been recorded the last 30 days. So why doesn't the Premiere record them? Really stinks having to go through the Guide and manually setting recordings. Don't want to set the Season Pass to Record Everything because I don't want duplicates. Is there a reason this is happening?
