Jerky picture playback on laptop

[Dimsum]

I encoded the pal version of Finding Forrester using the xvid codec and when I play it back on the my PC (which did the encoding) it plays fine - both picture and audio (mp3).

When I play the same file on my dads toshiba laptop, while the sound plays fine, the picture just stutters, yet progresses. Does anybody have any idea what could be causing this? He has the same xvid codec installed that I have. I just want to know if there is some option I need to select or not to prevent this happening.

I kept the default options when doing this and output to 1CD.

thanks

It might be a CD speed problem. You might try copying the file to disk to see if that solves the issue.

The file is playing off the hard drive, I copied it across from the CD.

Oh, well, it might still be a speed problem. As on any 1 CD rip, probably BR is not too high, but if the disk is slow or too fragmented you might experience a similar symptom.

Some ideas... Does the same thing happen with another file? With another player?

[Dimsum]

all other xvid files play normally - on both my PC and the laptop. This is the only file I have encoded using AutoGK - and while it plays fine on my PC, the problem only shows up on the laptop.

All other avi files I have, have been encoded using flaskMPEG or commercial converters and I copied some of these across to the laptop and none of these exhibit this problem.

If the problem was the BR, then there wouldnt be anything I could do about it as AutoGK has this autoset.

Thanks for the help so far!

what's CPU speed on laptop?
May be installing Nic's XviD decoder can help.

P.S. may be you have some other codecs installed on the laptop which are trying to play XviD (like latest divx for instance) and the problem is there. you need to carefully examine render path in GSpot and make sure it's the same on both PC and laptop...

Could be an overlay/hardware decoding issue - what kind of video chip is in the machine? I have a Dell Inspiron 8000 with an ATI Rage M4 chip, if I use the latest drivers from Dell, it plays back *all* mpeg4 content choppy (kind of like dancing infront of a strobe light, if you remember the 1980's ;-). I have to use older drivers from about 4 releases ago to get this working - any of the last 3 releases has some *improvement* that causes the same effect. Also, you can try moving the hardware acceleration slider around (there are 4 or 5 settings) in your display's property pages - one or two setting back from full acceleration may be better, I've seen this too with buggy drivers. Also, you may try *updating* video drivers too.

hello! cheers out ot len0x for his baby :)
i'm upping this thread coz i experience somthing very similar:
these are the common specs:
XviD-24062003-1 _ALPHA_ Release (version installed by autogk!)
2 pass encoding
1 audio stream: mp3 VBR (near 128kbs)
no subs
final size: 1400mb (2cd)

these movie play back nice and smooth onto my pc (using media player classic + xvid original decoding filter!)
BUT when i use 'em with my xbox and XBMC (i do hope i can talk about this...this is no ware stuff!) the video playback is evidently stuttering (it's pretty visible with fast side-scrolling and wide camera pans) - the audio part is nice
no PAL vs. NTSC issue here: everything is PAL format (original dvd, encoded xvid and playback machine)

i do consider this post would better belong to xbmc forums, but definitely it's something related to autogk encodings (otherly encoded divx play back fine!)

any clue :confused:

I have something like that to on my laptop. But only when i'm using the divxplayer that comes with divx. When I use powerdvd I'm not having that problem.:confused:
