</div>Good advice, perhaps you should say "spindle" and not "drive", as it's<br>
possible to have 2 or more logical drives on the same physical device,<br>
but that's getting picky :-)<br>
<br>
But to address the OP's original question. No, another tuner would not<br>
have any effect at all on the performance while watching a recording<br>
while making 1 new one. The only way another tuner would effect things<br>
would be if it were in use, and then the effect would be negative,<br>
obviously, if it were recording to the same device.<br>
<br>
If separating the DB and video doesn't fix things, look at your disk and<br>
filesystem performance. Modern drives should not have a problem with the<br>
situation you describe.<br>

</div></div></blockquote></div><br>Okay, so I'm taking it that the MySQL database takes up most of the resources for disk access when playing back and using frontend for general recording management? I do have the drive in partitions with the recordings on a separate part from the home/root, but a different drive would garner a more significant performance increase I'm guessing.<br>
