WMC7 Stutters During Playback

Greetings,

I am experiencing a unique issue with my WMC HTPC box. Anytime I watch content from either WMC7 or WMP7 I get audio and video stuttering every minute. Sometimes, the stuttering will cause the box to freeze up, forcing a restart. At no time do I receive memory warnings prior to or after each event.

I've tried restarting the computer in the hopes of clearing the RAM, clearing the Temp Files, and running ChkDsk (at the time of this posting, the process has taken over 1 hour to complete - not sure if this is normal).

I also installed Process Explorer to see if the issue was memory related. While it appears that WMC is hogging up to 3/4 of my RAM at some points, usage is mostly confined between 1.3-1.7 GB. The spikes occur regardless of the RAM usage but not when WMC is running idle (meaning ON but not displaying content other than the main menu).

Process Explorer appears to show that the issue is possibly related to SVCHOST - when I place my mouse over each spike, it displays SVCHOST but not the programs which that particular version of HOST is running.

I am running WMC7 64-bit, with two 500GB drives (one mirrored), a third drive (2TB internal) for video and music, 4GB of RAM, an Intel i3, a Hauppauge 1850 Dual Tuner, and a ASUS P7H55-M PRO motherboard. I will update with ChkDsk info when it finishes. Until then, any insights would be appreciated.

Chkdsk should take that long if you provided switches like "Chkdsk C: /f or /r"

Have you updated audio or video drivers

Have you receive any errors?

I've updated all the video and audio drivers (one of my first thoughts), but I need to ensure that I have all the latest - I will confirm and report back. I've also made sure I got the newest K-Lite codecs, but again there's the 32- and 64-bit versions. I need to make sure I have those as well.

Until I confirm these, do you think this could be a RAM issue? The issue happens with such regularity that I can't ignore the possibility that I need more memory.

What version of WMC7 Do you have Windows Media Player 12 the current version for windows 7 pro 64-bit is 12. Go to Help>>>Check for Updates

I don't think RAM is the issue as for I am running 4GB of RAM the only changes from you and me are the audio codes.

I use Shark007 codes list if you want to you need to uninstall your current codes pack and download the 32-bit install that pack (core pack) and installed the x64 components if you want to install it.

32 bit pack is http://shark007.net/win7codecs.html
and 64 bit pack is http://shark007.net/x64components.html

and I found http://www.brighthub.com/computing/windows-platform/articles/15296.aspx for reference of WMC7 hogging up ram.

Hope this helps

Thanks for these suggestions. I checked the versions of both WMP and WMC - they are both listed as up to date and share the number 7601.17514. WMC is Version 6, while WMP is Version 12.

As for reinstalling the codec packs, I uninstalled the K-Lite Pack. It appears I have Shark as well, but it only appears as a "You need to click OK to download the 64-bit version" which then takes you to the site to download it. Sorry if this sounds sophomoric, but isn't K-Lite and Shark supposed to be installed for everything to work properly? Also, aren't I supposed to download both the 32- and the 64-bit codecs, as suggested by your posting? Can't I just use the onboard codecs offered by WMC? I was thinking about these as I read the article you enclosed, in which the blogger suggested that I check DIVX for updates. So does this now mean I have to have Shark, K-Lite, and DIVX installed?

K-lite is the same thing as Shark007 audio codecs only differences is the various codes in the pack. I have only Shark007 codecs running on my system. I don't think you need all three as they will conflict with the other codes pack.

You can uninstall the audio codecs pack and use the on board codecs. See if its helps I didn't know that you had more than 3 codecs packs. It might be the issue here.

Yes you need to have the 32-bit version and 64 bit components to run the 64 bit version of Shark 007 codecs.

Sorry for the confusion

Ok, uninstalled everything Shark codec-related I could find and installed win7codecs_v290 and x64components_v293 from the links provided. Stuttering still occurred after v290, and also after v293. I used the Shark suggested settings as well and made no the adjusments. Any other ideas would be appreciated.
