I'm interested in a Roamio Plus box. I was wondering if it had the same annoying issue as my XL4. If anyone with a Roamio could test this for me, I would appreciate it. With the TV Preview window on (upper right corner) while going through a Tivo menu, if you push the live TV button or the guide button, does the TV preview audio stop and then restart and a black screen comes up for a quick moment? Thanks for anyone who tests this out for me.
