We are Able to watch all demand and the. Suddenly at 9 on every evening the service goes down on our TiVo box... we have Followed the steps for error code 603 at least 3 nights in a row... is there an explanation as to why it stops working and shows error 603 at the same time every evening?
The most obvious cause of OnDemand issues only at certain times would be internet speeds slowing down, although I have some doubts that's the main reason in your case.
When you next have problems, there's 2 things you can try...
1: If you're not recording anything and are able, try restarting your box - Home > Help & Settings > Clear or restart my box. I'm doubtful, if you say this error self-clears anyway (and it will interrupt any recordings), but it's something to rule out.
2: Regardless of whether you're recording or not... Home > Help & Settings > Help > (look along the top now) > TV Speed test.
