What tuners are available for Live TV after Recording?

[Wisegoat]

Not sure if the title accurately reflects what I am trying to figure out. Last night was my first full night with the HR20.

Here is the scenario I had last night:

Recorded the Angels/Mariners game on Channel 96.
Was flipping back and forth between that and live tv.
I padded the game an extra hour, but the game ran over that.
Since there is a 90 minute Live TV buffer, I thought I could flip over to that tuner, rewind and finish watching the game.
However, when I flipped to live tv, it was on the channel I had last watched while recording the game, not the game itself.
When I changed channels to 96, the game was already over and I could not rewind.
With the HR10-250, I could flip to the other tuner, the one that was recording the game and watch whatever was in the buffer.
Is there a way to access that "Other Tuner"?
Or is this related to Dual Live Buffers?

Hopefully I have explained this in a way that everyone understands.

I know we don't have Dual Live Buffers (yet hopefully), but the system should be smart enough to know it was recording that channel and when I change to that same channel, it should still be buffering.

Unfortunately you've run into a little quirk with the HR20 - it doesn't always continue buffering on a channel you're recording but you're not watching.

Yes, you could consider this an extension of the "Dual Live Buffers" brouhaha.

I'm sorry to hear you had this issue so early, I hope it doesn't discourage you from the HR20.

Thing is, when the HR20 is only recording one program, it does that on the background tuner. The remaining tuner is designated as the active tuner for channel changing and will always maintain the buffer.

When you're watching a program that is being recorded from within the recording, you're not moving that program to the active buffer. The only way to make sure you get all of the program is to increase the padding or jump to live before the recording ends.
