Better if you refresh your channel lineup - that just worked for the identical problem here and the option is active again while you are still viewing the program.
I am experiencing the same issue. It started I think about three weeks ago. At first it was just not showing on some of my shows, then eventually it was happening on every show I tried checking. One thing I did that seemed to work for a bit was on shows that I have set to record regularly. I set it to cancel the series then reset it to record the series and that seemed to fix it but that would only work for a day or two then it would go back to saying 'no other show times' (when there clearly was other show times). I tried doing a a regular search under the settings menu but was met with the same message about there being no other show times. I was starting to think it was just my PVR box DCX-3510-M but then about a week after it started happening everything started working perfectly again, so I figured it had been a Shaw issue that they had fixed. It seemed to work perfectly for maybe a week and now I am back to it saying there are no other show times no matter what show I check. I have no idea what the issue is but it mighty annoying. If someone could tell me how to do a channel refresh, that might help, however, I sure hope this is something Shaw is working on.
@MomOfARocker -- welcome to the month of May. Many TV shows have "wrapped" for the season. So, rather than showing reruns in the time-slot, they produce new shows for broadcast in the time-slot. So, there might not be any "other" broadcast-times, until the next season, this coming Fall.
Or, some shows, such as Tim Allen's Last Man Standing, are ending -- never more will there be any "new" episodes. So, the Shaw "Guide" could be correct.
What titles are not showing any "other times" (over the next 2 or 3 weeks -- the Guide only goes that far in the future).
No this is absolutely not the problem. If I click on any show that has already recorded to look at other shows times it says that there are none, however, if I then look in my upcoming scheduled recordings it does show shows the following week set to record. When I go into the guide or menu this is happening on every single show that I check so what you are suggesting is not the issue.
