I have a Roamio Plus that just recently has begun exhibiting this behavior (though since last couple SW updates). When deleting a folder from my shows, the TiVo reboots. That's it. It may not happen every time but is fairly repeatable. It can be a folder of 2 shows or 20. While I haven't investigated fully, it seems it happens with folders of all recorded shows or all streaming or mixture. Anyone else seen this?
