I have two original Tivo S3's. The first one's HDD died two years ago; I upgraded it with a WeaKnees kit.
The second one's HDD died recently, so I did the same thing. But now, on the one I upgraded today, I have no 'Video on Demand.' When I click that line on Tivo Central, the screen changes, then comes right back to Tivo Central.
Same thing happens if I go into the 'Now Playing List' and choose Netflix...screen changes, then returns without actually going to Netflix.
Everything else is working fine. I can transfer programs from the other S3, play back shows, etc.
On my other S3, connected to the same network, sitting side-by-side with the one having problems, it's fine. Shows the whole VOD page, with my options like Amazon, Netflix, etc.
Both are connected with CAT5 ethernet...not wifi.
Is there a setting I missed?
