I would like support for DTS decoding or at least DTS pass through.
You may ask why?????
Yes i agree, anything recorded off of OTA or cable TV will not be in DTS. So it isn't needed. I agree if that's ALL the programming that you watch.
However, I convert the blu-ray movies I purchase to my NAS which has TIVO support. Of my movie collection roughly 68% of them use DTS sound tracks.
Of those that do, 52% are using 6.1 or 7.1 audio.
My TiVo is connected to my home surround sound system which supports DTS 7.1 audio. If the TiVo had DTS pass through support. I could watch that movie on my TiVo and maintain my 7.1 audio.
Yes, currently my workaround is to use my roku 3 box, which does recognize the nas dlna server and does have DTS pass through. However I only have one of those and can't easily take it from tv to TV as needed. I do have Tivos on ever tv though. Plus I like to keep "boxes" to a minimum!!!
With pass through support, the TiVo doesn't even have to have a DTS decoder, it just sends the DTS signal down the HDMI or toslink cable to your receiver as needed.
