Netflix/stuttering HTPC

post #1 of 8
Thread Starter 
I have this annoying stutter/most of the time massive screen tearing on netflix with my HTPC. The machine has 4gb memory, AMD dualcore (I don't remember the exact model number), and an ati 5450. This is connected to a sony 52n bravio 1080p

When I play youtube for example, I get some crazy stuttering, and screen tearing.

I've searched around and I have found others have this issue; however the threads are old and there isn't ever a solution. Any of the pro's have any idea's?

What CPU and usage during stuttering? Netflix uses Silverlight which is not GPU accelerated yet.

You can open up the statistics overlay using: Ctrl+Shift+Alt+C
You can lower bitrate to reduce network and CPU load: Ctrl+Shift+Alt+S

That shouldn't matter for Netflix. Netflix checks your internet connection and sends you a stream with bitrate appropriate for your internet speed. The bitrate also adjusts throughout playback as the speed of your connection changes.

@twistedbran
On the tearing, are you using Windows 7 and do you have Aero enabled? As DuckieHo mentioned, Netflix is pretty heavy on the CPU. From experience, the lowest CPU I've used that can handle Netflix is a Celeron E3200 2.4 GHz Wolfdale level which is probably roughly equivalent to Athlon 64 X2 3.0 GHz Brisbane.

I get stuttering in Netflix quite often as well, Athlon X3 3.2GHz, 4GB RAM, 4850 1GB.. So it's got plenty of grunt. I always passed it off as a silverlight issue.

True, there appears to be an issue with Silverlight rendering that manifests as stutter for people with particularly sensitive eyes.

However, the tearing suggests either refresh rate is off or the CPU is too slow at decoding.

Sorry for the late posts. It is wireless; however my downstream is stable I get constant 1.5-2mb/s download rates. The screen tears, now I've just got some micro-stuttering...
