Someone already chimed in, and this response is pure overkill, but I posted this in another thread and may help anyone confused about buffers and channel selections with DoublePlay by demonstrating some of the capabilities of DoublePlay. You can swap between tuners and then change to multiple channels on a tuner and use PREV to switch channels and DOWN to switch tuners.
With DoublePlay, the receiver can keep track of up to 4 channels per tuner, so you can use YELLOW/Previous to cycle between them on one tuner. Tracing through these steps should demonstrate that the buffer remains intact when swapping tuners, but when using PREV or YELLOW/Previous Channels to switch channels on a tuner the buffer is flushed.
Most people will be content to just press DOWN to toggle between tuners, and at most may switch between two channels on one tuner while never switching channels on the other tuner, but this demonstrates the full potential of DP with the independent channel tracking per tuner ...

This version of DLB is ok. Except I am tired of being asked if I want to cancel dlb when I am changing the channel and one program is already being recorded. Just change the channel.
I had no idea this feature was coming. But today, my 18 month old was playing with the remote and he activated it. I was so thrilled to see it, because that is one of the things I missed from the old Tivos.
This is one reason for not enabling DoublePlay in the first place. This conflict message will not be displayed if DoublePlay is off.
If you are recording a channel, why would you have dp activated in the first place?
you can be using dp then a scheduled recording starts.
But his(?) question was concerned about a channel that is already being recorded, at least that is what I got out of the post.
So here is what was going on.
I was recording 2 things previously. One of the recordings was over and I was done watching the program, but the other recording was not. We were recording 13-1 and 537. We started watching 13-1 about 20 minutes in and the show we were watching got done about 5 minutes after it was done recording. 537 was still recording. When I tried to change to the channel 3-1 after continuing to watch 13-1 for about 20 minutes after the recorded program ended. When I tried to change from 13-1 to 3-1 was when I got the message. Problem is 13-1 was not being recorded at the time even tho the message said it was. It confused me and had to read it a few times to make sure I didn't stop recording 537. Tivo wouldn't ask this and possibly confuse me.
If what you are saying is correct, then in this situation, I think I would expect you to have changed channels just fine from 13-1 to 3-1. If you were on the tuner buffering channel 537 when you tried to change to 3-1, then you would have received that message as DoublePlay would have been turned off so the background tuner (13-1) could change to the new channel.
Somewhat related situation where I found the behavior quite annoying:
I was using DP to watch a couple of games. On the active buffer, I wasn't caught up to 'live'. I wanted to start a recording so went into the Guide and used Record (it was on 'now'). I had expected it to record on the background buffer, but instead it started recording on the active buffer, so I never did get to see the end of the game I was watching.
Yes, when DP is activated, you work with each tuner separately. Whether it is previous channels or record from the guide, you now only affect the current tuner.
Yes, if DoublePlay is active and you search the guide for a show, it will use the foreground tuner. This is different than if DoublePlay is not active.
Using DP and I just noticed......
When buffering a tuner in the background, it seems to "dump the buffer" when a new program begins.
That's no gouda...
Can you please expand on this? Let us know what was on Tuner A, what was on Tuner B, and where the new program was starting (which tuner). Also what do you mean by "begins"? It's starting to record?
Also, remember that the time bar display will only show the current show. You have to REW to 0, then keep rewinding to access previous shows in the buffer. Make sure you try to do that.
Keep rewinding, it's still there.
I use DP while one tuner is recording. Say a program you watch starts recording on tuner 1 and you decide to watch it live. When you get to the commercial, pause, start DP to swap to tuner 2. Then start watching something else or channel surf. Then swap back to tuner 1 and continue to watch your original show.
I've even used DP the same way when both tuners are recording. Prior to DP, I was using [Prev Ch] to swap between 2 live recordings. The problem was that instead of starting where you left off, many times it would start at the beginning again. It was very annoying.
Instead of going to the guide to record the game, while watching the game you want recorded, you should just press [REC]. Then it would have left the buffer in the other tuner intact.
Just use the previous button. I just tried it. started recording ch1, went to guide and picked a second program. Pressed previous, back to ch1, pressed pause, previous button and I'm on ch2, previous button back to ch1 where I had paused it. Ch2 buffer will be flushed.
If you channel surf, even with dp, the buffer will be flushed on the surf channel.
But to each their own.
