I've heard antivirus software can interfere with performance of MC.  Recent play of a bluray was hogging alot of my cpu usage... occasionally hitting 70-100%.  Granted I had a few DSPs running...

I am uninstalling my norton 360 antivirus to see if there's any change.

In the mean time, as there known alternatives?  Obviously nobody should run a windows machine without antivirus, and many of them do not allow you to turn them off or stop them in task manager.

I've had success with avast, avira, and AVG by just making sure to exclude:
The JRiver folder(s)
All folders with the media in them

After exclusion, restart PC


I'm not sure how that works with the optical drive, I know if you do an install from a CD drive the AV will kick in.

I use Norton 360 with MC on the Server and my Client, and it is fine. In fact it is very good software now.

Just make sure it is not running in silent mode, so that you will see any popups it generates when it is taking some action, such as blocking an application. Get it to ask what you want to do when it does need to take action.

Also exclude the executables from being interfered with by the firewall. I don't even exclude my media locations, but if your PC is struggling with processing power, that may be a good idea. I should really do that myself.

See this thread for some hints. Not the same situation as you, but you will get the idea. http://yabb.jriver.com/interact/index.php?topic=103104.msg715944#msg715944

Hmmm... uninstalling norton didn't seem to fix/change anything.  Still getting pops/clicks when playing this bluray.  I can see the cpu usage spike when it happens.

That's good. Then it wasn't Norton, so long as you rebooted once more after completely removing it (that last reboot makes sure the system starts "clean" without the kernel drivers from the AV application still running). Assuming you did that (and the uninstallers usually make you), you can reinstall it if you want. Norton 360 is certainly not "well respected" as being the most well behaved AV application out there.  But, it should be possible to get it to behave generally with MC (if you have issues, which it seems not in this case) with something resembling these steps:
http://wiki.jriver.com/index.php/Taming_Symantec_Endpoint_Protection

Note that you almost always have to separately exclude filesystem locations (primarily the MC Library itself, and its AppData locations, not necessarily the media file storage location) AND the individual running processes. In fact, the latter is more important than the former, in most cases.

But, as I said, your particular problem seems to have been ruled out as being caused by Norton in this instance.

Otherwise, it might be best in a new thread because this thread title isn't really applicable anymore, but if you want recommendations on improving performance, we'd need:

* What kind of hardware do you have?
* What OS is it running?
* What drivers do you have installed for the GPU?
* Are you testing with decrypted discs, or are you running an on-the-fly decrypter (it could be some issues with that process)?
* What settings do you have enabled in MC (especially under Tools > Options > Audio, Options > Video, and the DSP)?
* Did you mess with any of the default madvr settings (assuming you're using ROHQ)?

Convolution filters and resampling, in particular, can beat on your CPU if you have an underpowered one. The GPU settings could also come into play, especially if you've done anything to customize madvr.

Just to be sure, did you reboot?

You can also try running the benchmark by going to Help > Benchmark... and post the results here.

Another vote for the hardware not being fast enough.

Please run the benchmark and report back.

A little slow, not good, not terrible.

I actually removed a few automatic processes from task manager and the performance improved.
