I ripped a copy of a couple of my Planet Earth DVDs to my HDD using Mac the Ripper, and I noticed that they stutter (almost imperceptibly) when playing back. They are just SD versions. Do you think the problem is occurring during ripping, or playback? Are there any settings I can change in MTR to fix this?

Try ripping it with lower settings to see if that helps. That should at least narrow down the problem.

did you just do a full disk extraction with MTR? did it give you any warnings when you started? does the disk play fine through DVD player? does the VIDEO_TS folder play fine through DVD player?

How did you rip it (what settings)? What are you playing it back on? Planet Earth in High Def tends to be the ultimate test of computer's playback performance. If you ripped it at a crazy high bitrate, even standard def will give the software decoders fits.

He said he ripped the SD DVD, and used Mac the Ripper, so it is just a direct rip of the DVD, and wouldn't be encoded as anything else (MTR is just a DVD ripper not encoder)

What are your system specs like, and is there anything else running in the background?

Uhhh, lets see..

I just did a full disk extraction, and probably didn't have much running in the background while it ripped...maybe just firefox.

I'm running a 1.66 GHz mini with 2 GB and leopard.

I never noticed it stuttering while playing the disk, but then again, I wasn't watching it 100 inches across either. (I just hooked up my HT to a projector) I'll have to try it again just watching the disk.

you should have no problem playing this ripped DVD.

i would try the disk on your current setup (with the projector, as an aside - what resolution is the projector?)

Are you playing the ripped disk through Front Row? DVD Player? VLC?

try another option other than the one you are/were using and see if the stuttering is still there.

Does anyone have the HD version of Planet Earth. I have them, but I don't have a mini yet. Looking to get one soon though. What is the play back like?

Thanks

I have them as mkv's. They are the ultimate workout for VLC. Some of the playback is good, but frames are dropped frequently because of the high resolution and bitrate. I think this is because the h264 decoder isn't as optimized as it could (will?) be and not because of the mini. I love this little machine. Can't recommend it enough.

Ye VLC is to great at decoding high bitrate h.264 videos it tends to leave alot of the processor unused even when frames are being dropped.

How far are you uping the resolution on the video.

Let me explain my issue i have a 2.0 ghz 2 gig ram 120 gig hard drive intel mac mini i go to run any video in the mkv. format even under quicktime and the video is extremely jerky and doesn't play right and when i go to play it under vlc it tells me my computer isn't fast enough to run the video.

Now i found out why this is happening the mkv i have is coded in a windows video incoder format that is no longer used.

This happens when downloading videos and the person or persons won't update there software.
