I hope this isn't the case when it's officially released. It seems like they just mention the Q will have to be hardwired, nothing about regular Premiere-to-Premiere MRV streaming. That would really tick many people off including myself who don't have the option to go the hardwired route.I totally glossed over this the first time I read it but it appears RCN has confirmed that 14.9 MRS will only be supported for hardwired Premiere's and Previews. I'm guessing that TiVo will disable MRS support if a Premiere is networked via a WiFi adapter. It sort of makes sense that TiVo is doing this since it will cut way down on support calls due to WiFi network issues.
My current Premiere and Premiere Elite are streaming right now via hardwired ethernet.
