1080i or 720p between your 6412 and your TV and you use Digital AV3 output to your audio system that you never loose the AV3 signal and have to resync your audio amplifier. Is this correct?
Yes, this is correct. With the HDMI connected to the TV I would get flaky audio through the optical connection into the HTIB. Sometimes it was AC3, but as soon as the channel was changed to a non-digital audio program OR I did any DVR function (pause, replay, etc.), I would lose the AC3 audio for good. Sometimes I would lose the audio completely. (Comcast box has no way to set PCM vs. AC3)
With the component video connection, everything seems to work as expected. It is AC3 when it should be and PCM when no Dolby audio is available. No need to reset the HTIB and recorded DVR programs now play with 5.1 surround.
It kind of sucks that I have to settle for either digital audio OR digital video but not both. The 6412 does not do as good a job as my TV in scaling the video content, and the audio system doesn't sound nearly as good with the analog stereo connections. The 6412 is a very buggy piece of equipment, and I can't say I'm thrilled with it.
