Only one tuner used for back-to-back overlapping recordings

    I think that when it was first reported in September, the feature was only on the Roamio models. Then the feature was disabled. Then the latest release re-implemented it and added it to the Premieres but the problems were still there.

    The good news is that the "glitch" is minor and it doesn't seem to prevent transfers to the computer. Still annoying though.

    I have the same issues. the second recording is blank for the overlap period, then starts from that point to the end.

    I think the idea of using the same tuner is a fine one, but the implementation definitely needs work.

    The problems we seeing are exactly why I did not want TiVo doing something like this until they fixed their deeply flawed s/w development process.

    The way this feature is working smacks of a "quick & dirty" solution.

    I'm still getting the glitching on back to back recordings.....about 1 minute in and it's driving us nuts.

    Tivo really needs to turn this off until it's proven ready in beta.

    TiVo's programmers probably need to move the overlap block duplication code to a lower priority background task where it won't cause glitches in the main recording task. Or maybe they could just allocate more video buffer space to the recording tasks. Has anyone ever determined that the Roamio has more RAM than the Premiere?

    I had the NFL game scheduled to record an hour long, then I had 60 Minutes to also record an hour long. It recorded the game fine with the hour extra, but totally ignored 60 minutes show. Most of 60 Minutes was in the hour padding. In the history it says did not record because it was not in the guide. I tried it prior with a short overlap, but I guess the length of the padding caused the issue. The two recordings were scheduled back-to-back. Yes I know that I could have modified one to prevent the overlap, but was interested to test the new feature.

    I've seen that issue reported by someone else. I think astrohip reported that behavior in the Premiere forum. Obviously this code isn't working right with large pads that overlap entire shows.

    I had the same issue with the animated FOX stuff on Sunday. My SPs have padding in them ( 1 minute leading and 30 minutes trailing for "The Simpsons" and "Family Guy" and 1 min leading, 1 hour trailing for "American Dad". It did not record "American Dad" at all ("No Longer in Guide")

    Probably wouldn't have helped. Since FOX had the early game, I reduced the trailing padding. All it did was create two blank entries in the ToDo list and leave the existing padding in place.

    I have started a thread on the tivo.com forum for scheduler problems. (I spelled scheduler wrong over there. :eek:)

    Good memory! I've discovered any time a padding completely overlaps the next show on the same channel, that next show does not get recorded. The only reason I'm not ballistic is it's recorded as part of the overlap, so I can just FF to find it.

    But still... fix this!

    Unfortunately, sometimes the next show will not record even with a small overlap (no longer in guide message). This issue was fixed for a short time and then re-introduced in 20.3.8, which is the most annoying part. Here is one of the original threads from October discussing the issue:

    If the padding contains the entire second show, then most likely the padding wasn't necessary. This is rarely the case.

    I emailed Margret about this issue yesterday. Her and I had emailed about the issue back in early October when it first showed up. I'll share if there's anything newsworthy.

    Wish they'd get this implemented, and correctly! Directv has had this feature for years. Extremely useful on Sunday nights! I record all shows on Fox's Animation Domination, and because of football, tell each show to record an extra 3 hours. On Directv's DVRs, all 5 shows can be recording at the same time and it's only using 1 tuner, leaving the other 4 free for other shows.
