I have my Tivo connected to both the HDMI input and the AV input. Usually, I would use HDMI as the quality is better.

However, on occasion I notice that one of two things can happen -
1) The TV can completely fail to find an HDMI signal. I need to switch off the TV and switch it on again for it to work.
2) The picture is visible, but it takes about 5s for the sound to start working.

In all cases, the AV input works fine without delay.

I'm wondering if this can be down to a weak HDMI signal, or the TV finding it harder than normal to identify the signal as 1040i (I have the Tivo set to Fixed output)? ANyone else experiencing this?
