hey there. im new to these forums, but not even close to being new to trying to find a solution to my problem...so i come here begging for help.
the main problem is that my HD movies do not play smoothly. they jitter at some points (looks like a lower frame-rate for example...) and also the brightness of the screen changes for 5-10 seconds to a much brighter display, then goes back to "normal". During this brighter period, I see a lot of pixelation of the picture.
Also, I do not experience any of these issues with SD content.
This is not a network/wifi speed issue as I have tested this with movies that have been fully synced to the AppleTVs hard drive. On top of that I have a fast wireless N network setup anyway...
I have tried both using the HDMI port and the component + optical out and get the same results.
I have dozens of HD movies that I have converted (using handbrake) from mkv to mp4 files that sync and play easily on the apple tv. I start with the AppleTV preset and then have adjusted settings til no end and still havent been able to find a setting that works.
I have tried adjusting the bitrate setting anywhere from 4,000 to 7,000 and have not solved the jittery issue. At 4,000 I loose too much quality as well. 6,000 has given a good picture, except for this crappy playback issue. I have also tried Constant Quality settings from 45 to 20 and those didnt help solve the issue at all.
After it appears I have removed many of the variables, the only conclusion I can draw is that the processor of the AppleTV just cannot handle the "intense" HD movie files that are being thrown at it. It must struggle to display the image, similarly like an older computer with a slower processor would.
The icing on the cake is that I do not experience any of these issues when I playback the video within iTunes on my MacBook Pro. This is what leads me to believe it is the processor of the AppleTV that cannot handle the video file.
Any input or help someone can offer is greatly appreciated. These playback issues have been driving me crazy for a long time and I cannot find the answer....
