How to have 2 channels buffering at the same time (Single Mode):
1.Let's start from when you power on your 625, 522 or later HD model DVR's. The channel you are viewing live is buffering (don't change the channel or you will lose what has been buffered) or change the channel to the desired program.
2.Press the "Swap" button. The channel you were watching is now the background tuner continuing to buffer. Now, you may change the channel of the foreground tuner you are now viewing to whatever you like, and this tuner will also buffer.
3.Simply press the "Swap" button to change between tuners without interrupting buffer process.
4.You can also use the "PIP" button and functions for the same results.
All trick play is available for each tuner during buffer. Each tuner running in this mode has a buffer limit of 2 hours.
If you wish to view a DVR event (that has been previously recorded). then only the background tuner will continue to buffer. The video that you are tuned to or watching in the foreground will no longer buffer. This is the same action as if you were to change channels.
To have a tuner buffer while watching a DVR event:
First, make your buffered channel the background channel. If it is not the background channel, then you can tune to the channel, press "Swap" then load your DVR event. Or take the channel you are currently watching in the foreground and press "Swap" making it the background tuner, and now load your DVR event.
If you want the foreground tuner to "buffer" as well, the work-around is that you have to use the "Record" function. You can add time to the end of that program by selecting "Options" when you press the record button. Or you can set a manual timer for hours and hours of time. But each tuner is limited to a 2 hour buffer unless you use the Record function.
I hope that was clear enough to help.
