Xbox 360 h.264 HD video playing back skippy - Need Help

[cbstryker]

I have encoded over an hours worth of home HD video with both TMPGEnc 4.0+ and the latest release of Badaboom to H264 in mp4 containers. The videos play back fine on my computer, but as soon as I view it on the xbox (either from a disc or a flash drive) the video starts just fine, but after a few seconds it starts to stutter (going at about 5fps) but the audio is fine.

Now if I pause the video or skip ahead the video is fine again for another few seconds and starts to stutter again.

I've set the bit rate at 4500kbps in each encode. I know that the xbox can handle that since I have downloaded videos at much higher bitrates than that and they all work fine.

Does anyone know where the problem may be?

Thanks in advance.

Have you ever had success playing such files on the xbox360 before ? ... I mean those you have created, not those you downloaded from other sources

If this is something new, then check your xbox360's firmware is updated beyond september 2007.

Ya I have the latest xbox update (NXE) and I play aplenty hidef content all the time. I download a few tv shows in HD every week and I never have any problems. The only thing I can think of is that the videos I'm converting are coming from an AVCHD source, which I can't see that as a problem since the output file should be 100% compatible, but maybe I am missing something.

edit: Sorry, I just re-read your post. I have encoded my own HD content before, but never from an AVCHD source since I just bought my camera about a month ago (getting the files to play was a whole other matter). My camera is the Sony HDR-SR11.
