Thoggen produces jittery videos

I've used Thoggen to back-up several DVDs, and I discovered that the resulting OGV files have very stuttered video playback in MPlayer, Totem, and VLC.

Since I hadn't encountered the jittery video before, I tested it with some video files I've downloaded from other people. A mix of MP4 files, OGV files, and WMV. I found that the WMV got jittery, too (especially during intense scenes), but the OGVs and MP4s played back perfectly smooth. Only the videos I've ripped with Thoggen have stuttered video playback.

I'm using the preferred DVD ripper and the basic playback applications all on default settings. Has anyone else encountered this problem?

Can you upload a sample (you can create one for instance using FFmpeg) so others can test to see that it isn't a graphics card issue?

I probably should have mentioned, my netbook is pretty light with just 1 GB of RAM and a processor probably in the 1-2 GHz range.

I'd gladly upload a sample, but I'm suddenly wondering if it's a quality issue. Is it possible that my netbook struggles to decode higher-quality videos? I can try decreasing the quality when ripping with Thoggen and see if I get better playback.

Netbooks usually do not have a good graphics card that supports video decoding and thus video playback uses the CPU. Since the CPU is weak (e.g. Atom) playback of high quality videos (e.g. 720P) isn't smooth. (720P video also needs to be rescaled as the typical netbook resolution is lower than that.)

This thought just didn't occur to me. Anyway I'm reasonably sure I just need to turn down the quality a bit when using Thoggen.

Is there a way for me to edit my post title? It now seems misleading.

I don't think it can be changed. But don't worry, at least half of the internet is misleading.

That is somehow reassuring ;-)

Try k9copy. It works fine here.
