    We bought the TiVo HD on Wednesday (which we've had to since replace) and when we got it set up we've noticed a few minor glitches when connected with an HDMI cable

    firstly on any resolution above 480 there is a solid green line down the right hand side of the screen, slightly annoying but livable, I'm just wondering if anyone else has this issues as it's occurred on both systems we got.

    The other issue we had on the first box was if we watched a recording (or anything other than live live tv) the screen would pixelate and jump around, thankfully the new box has sorted this.

    what model of TV do you have and what resolutions does it support?
    Are you hooking startight to it with the cable or is there some video switcher or other device in between the TiVo and TV?

    It's a Philips and it supports 1080i and 720p, it's connected directly from the TiVo to the TV

    Have you tried a different HDMI cable or tried the same cable with another component?

    I used HDMI to my Samsung HL-S6187W for my review and I don't see any green lines.

    What happens if you set it to fixed mode for 720p and for 1080i? Perhaps it only occurs on one of those modes?

    I haven't tried 720p fixed, but I normally use 1080i fixed. I mostly used it in 1080i fixed, but I also played with Native.

    Does the line "flicker", or is it solid?

    If it flickers, your TV probably isn't overscanning. What you're seeing is the closed caption information.

    It doesnt flicker, it's solid, and appears in the TiVo menus also.

    We've tried 2 different brands of HDMI and both gave the same result, and unfortunately we dont have anything else that outputs HDMI to test this on, this is the first time we've used it

    changing the formats makes no difference, fixed, hybrid, native all green lines

    Weird. Sounds like a bug somewhere; if you replaced your tivo it can't be a hardware issue. Try calling tivo customer care and complaining. Until then just use component, it looks identical anyway.

    Sounds like your TV's HDMI input might have a problem or perhaps some other problem with the TV. Not a happy prospect, but worth considering. It seems others are using HDMI and it's working okay. If both Tivos are doing the same thing it makes me wonder if the TV might not be the culprit. You'd have to swap TV's or try another HDMI source to know for sure.

    I have a philips set and had a similar problem with another component. The TV remote has a circular input ring on it. This ring can move the picture up/down/left/right. Try to move the picture around to see if you can eliminate the green line.

    using 1080i fixed probably won't give you the best picture anyway. Either let the tv display the signal in its native resolution pr fix it at 720p.

    It depends on the set. My set is 1080p native, so I use 1080i fixed and let the set de-interlace. At 720p it would have to scale everything, and any 1080i content would be scaled and de-interlaced by the TiVo, then re-scaled by the TV.

    I used to run Native, the picture wasn't better and it made the TV got nuts for a second each time the resolution changed as it locked onto the new signal.

    I never could get used to the funky resolution changing and it and it was a happy day when somebody on these boards mentioned they had started using "1080i fixed" and it had made all the switching around weirdness stop. It cured one of the only problems I had with way the new HD stuff worked. It'll be nice if one day they can all just broadcast the same resolution and 16:9 but I'm guessing that may be a long way off. :p

    My TV also does funky flashing when switching resolutions. I have mine set to 1080i fixed (it's a 1080p LCD) and it works great. It does stretch the 480i screens so people appear a bit wide, but I much prefer the full screen stretched look to the black sidebars and the funky TV resolution switch.

    I have seen the green and purple lines during a brief moment during a resolution switch. I was able to take a picture of it:

    [​IMG]

    This is an image taken when changing the channel from a 1080i HD channel to a 480p channel. They only appear for a fraction of a second as the TV switches resolution. I would have to make a guess that your TV isn't quite shifting the image far enough to the right. There may be a setting on your TV to adjust the image. I'm pretty sure my Westinghouse has that function (though I've not needed to use it).

    We use the 1080i fixed format as anything else causes a brief flickering when changing resolutions, and regular 480i looks OK upscaled to 1080i.

    I do think it's a TV issue now, I've not seen a place where we can adjust the screen area yet, but I'm looking into it

    thanks for the advise

    This solved it!

    I feel somewhat retarded now ;)

    I was looking in the setup menus for this and never thought to press the buttons outside of it
