Turn off the blu ray, goes back to tivo.
Just potentially beware of Sony Bravia TVs. Many of them (as reports from others have proven, beyond my own experiences) have a hard enough time doing HDMI direct with base-Roamios, and a switch makes things worse (I've tried several, and many different cables).
The monoprice switch I've tried (out of a few brands), but only worked for me before my base-Roamios: http://www.monoprice.com/Product?c_i...seq=1&format=2
4X1 Enhanced HDMI® Switch w/ Built-In Equalizer & Remote (REV.3.0)
Product ID: 4088 (HDX-401E)
I think the "built-in equalizer" might be the biggest issue-contributor (for my scenario). I've also had the roughly the same issues with base-Roamios and a Samsung TV.
The current Roamio software helped resolve most of my direct-link issues, but the HDMI switch results are still what I would call "undesirable".
There's a lot of "YMMV" involved with HDMI switches. The same one I listed (as well as those I didn't) worked with TiVo HDs and Premieres, with the same TVs.
