I just built a new system and I noticed VLC/Media Player Classic and other players are choppy when watching AVI files. MKV files seem to be OK, but AVI (DivX, Xvid, etc) all seem to start playing but gets choppy shortly after. Flash videos on say Youtube are fine up to 1080p.

I've read quite a few sites online saying to turn on hardware decoding and such which I have, and they seem to help a little but nothing substantial. I went from a AMD x2 6000 running the same videos flawlessly to my new system being so choppy I have to turn the video off (by sheer annoyance). I should note that I'm streaming it from a file server I have running, but that ran fine even on my old system. I tried copying the video locally and same problem.

Things I've tried:

1. Disabling (and re-enabling) Intel SpeedStep
2. Disabling (and re-enabling) C1E
3. Setting affinity to VLC/MPC/WMP to 1 core

Whats frustrating is that gaming is AMAZING, but something as simple as a top gear episode jitters. :fou:

Here is my current build (I should note I used TH to piece it all together, thanks for all the reviews!):

CPU: Intel Core i7-2600K Sandy Bridge 3.4GHz (3.8GHz Turbo Boost)
Memory: G.SKILL Ripjaws X Series 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800)
Motherboard: ASRock P67 EXTREME4 (B3)
GPU: EVGA SuperClocked 012-P3-1572-AR GeForce GTX 570
PSU: CORSAIR Professional Series HX750
HD: Western Digital Caviar Black WD6401AALS 640GB 7200 RPM SATA 3.0Gb (2x in a raid 0)
Wireless: Linksys WUSB600N (connecting at 270Mbps)

PS: I will be going SSD soon but it wasn't in my original build cost.

Any help would be appreciated.

At this point I'm just going to chalk it up to a random weird issue, I'll swap out the mobo and if that doesn't solve it I'm just going to throw in the towel. The videos work on the primary screen just fine so I'll just run it that way.

It plays games perfectly so I'm not going to rock the boat any more then I have to.

Thank you for all the assistance Pyree!

Just an update.

I RMA'd the motherboard and that didn't solve it.

I swapped the video card for my old 8800GT and that didn't solve it, so its not a GPU / driver issue.

I'm going to swing by the local computer store and pick up some different RAM and test with that, if that resolves it I'll be returning my current RAM and trying something different..

Did the new RAM help? I have a similiar setup and was noticing some choppiness with my setup. I have the same RAM and cpu. I'm wondering if the 4GB is just too much for 1 dim/stick of RAM

It didn't.

BUT, I figured out the issue. I feel a little stupid but I've NEVER had to check this before.

I went in to the physical monitor settings (Windows Configuration, not nVidia's) and it showed the refresh rate at 60 Mhz (which is right for my LCD's), but there was another option for 59 Mhz. I change it to that and BAM, everything is working better then amazing.

I have no idea why, but it must have something to do with drivers or something, but I can't be happier with my setup now.

This settings worked for me :-: I have "K-Lite Codec Pack" installed...
Try this:
With "Media Player Classic" open, go to OPTIONS > REPRODUCTION > OUT
Video DirectShow -> Choice the first one => SYSTEM DEFAULT > Apply > OK
Close and reopen the "Media Player Classic"...
Done.
