I have 2 Premieres, an XL that is not currently being used and has no current subscription attached to it, and a Premiere 4 that has an active subscription and is in use as the only DVR in the house. My question is this. Can I use the XL as a second unit in a multi room setup, if I connect it to my network, without a subscription? I realize that if this works it will never be a tuner but just a "slave" unit that allows playback only in another room. Thanks for any info.
