Online User Manual:  R5000-HD DVR

Time Shifting
The R5000-HD can be made to be part of a time-shifting network. As a recording is in progress, the file is accessible by other playback devices which can be used to simultaneously play it. The stream can be paused or rewound as desired by the viewer. Recordings can also be made to a networked drive and played back through other networked decoders.

However, there are some limits to how successfully all this can be accomplished. A lot will depend on system resources and speed if the playback device resides on the same computer as the R5000-HD. You should avoid attempting to do any kind of multi-tasking while a recording is in progress until you have a feel for your systems performance limits and feel comfortable that it won't affect your recordings. Using Windows Task Manager can give you a good indication of how much your system is being pushed. Below is a shot of a R5000-HD recording in progress with MyHD switched on for playback (note the jump in usage).

Anytime CPU or memory usage is close to maximum, then there is cause to worry. Also, examine the "Buffering" shown on the R5000-HD main dialog. If you are consistently "Pushing it" or you cause a buffer overflow to occur that is an indication the system resources are too low (see "Main Dialog" section). The R5000-HD is already set to run at a high priority. It is not recommended nor is it necessary to bump it to "Real Time". Launching applications (especially memory-hogs) while a recording is in progress can cause large usage spikes that should be avoided.

If your playback device is networked then obviously over-utilizing your PC resources is not a problem. However, the limiting factor in your success maybe your disk throughput or network performance. Luckily, caching seems to favor writing to disk and most of the time only playback is affected.
