multi-room does not work with DVR stored on external hard drive

I am not getting anywhere with Verizon and am about to chuck it all and go with ATT Uverse!

But I thought I'd ask here first.

I added an external hard drive as Verizon said I could and it works great except for 1 minor problem.

I can't see any shows on the external HD from any device except on the avtual DVR.  So if I'm in the same room as the DVR, no problem.  Any other room and I can't see any shows except those on the internal HD (which are the oldest and already viewed).

Anyway to put the newest shows on the internal THEN archive to external?

Or, better yet, has anyone else been able to figure out how to watch a show that was recorded on the external HD from another receiver?
