I have a high resolution video that stop and skips during playback. Sound is OK though.

The .mp4 video is:

Codec: H264 - MPEG-4 AVC (part 10) (avc1)
Resolution: 1920x816
Frame rate: 23.975686
Content bitrate 4100 kb/S

The Audio is:

Codec: A52 Audio (aka AC3) (a52 )
Language: English
Sample rate: 48000 Hz
Bitrate: 448 kb/s

Playback is fine on a 1.6 GHz dual core laptop using VLC. I would think that the a the 2.4Ghz Dual Core with MythTV would be enough processing power. Myth Hardware details are in the signature below. I think that this is a software issue and not hardware.

Question: What tests can be performed to determine a fix / correction? Specific system commands and any experience with this problem would be appreciated. Thanks.

Are you using/have you tried the internal player? Mplayer?

@poflynn: yes. I am using the native video player. mplayer??
I think, but not sure if this is the mplayer version info:

You don't mention graphics card or hardware acceleration. A newer NVIDIA with VDPAU enabled on your box would make an enormous difference to playability.
You would use the "-vo vdpau" option for mplayer if that's what you are using to play the file.

I am using a JATON VIDEO-338PCI-TV NVIDIA GEFORCE PCI 6200/256MB with a SD TV. I don't have an HDMI monitor or I would try it out with the MOBO's HDMI output.

@Mike, which file would I need to make the suggested change? I am using the default video player. I do not know if it is mplayer. Is there a command or setting that I could check to verify? Thank you for your guidance.

I have some slight stutters and skips with 1080p h.264 on my Dual Core Athlon64 system. The internal player just seems to struggle with 1080p H.264. My solution was to re-encode to 720p since I have a 720p TV but obviously that might no be ideal for everyone.

the 6200 chipset doesn't support VDPAU so that route won't work. You might consider buying an 8400GS, they're pretty cheap.

I have no idea if your CPU is good enough to decode this file BTW, if it is and there's some other problem, then buying an 8400GS will be a waste of money.

Try running mplayer from the cmd line (alt-x) to see if it spits out any msgs about your system being too slow.

I am assuming the file is on a local HD & not a network share of some sort.
