Following a restart (not sure whether it was a TiVo restart or a laptop one) the downstairs TiVo and the laptop have disappeared from the bottom of the "Now Playing" list on the new lounge TiVo.
The downstairs TiVo still 'sees' the laptop and the lounge TiVo, but it cannot access the programs to transfer from the lounge TiVo.
The lounge TiVo can access the wireless home network and connect to the TiVo service.
I have checked the network settings on each box (Messages and Settings>Settings>Network>View network diagnostics) and the DNS resolution test has succeeded on both, but the Port Config test has failed on the lounge TiVo.
The downstairs unit has a list of available ports (37, 80, 7728, 7287, 8080, 8081) and the lounge unit just says "Failed" and advises that I connect to TiVo to download a list of ports and then returned to the diagnostics screen again to re-run the test.
I have followed these instructions a number of times with rising levels of frustration!!
I have also restarted the lounge TiVo (with the downstairs machine off and on) and restarted the laptop a number of times.
Does anyone have any ideas how to fix what was working fine?
