Recently my video codecs went a LITTLE haywire and I had to download and reinstall a WHOLE new pack. I did this with the k-lite mega codec pack, and now all my avis and mpegs are working again. However, I noticed that now when I try to play dvds on my computer, the picture has this strange quality where any onscreen movement is jumpy, almost like its vibrating. It's incredibly distracting and actually GIVES me a headache if i watch it too long. Im assuming that it's related to the codecs reinstallation, because I previously had no problems with watching dvds. I'm running a windows xp media center computer with an ATI Radeon x300/x550x/x1050 video card. any advice would be much appreciated.No actual answer but - am curious as to how files might play in different players. I hate Win media Player but do use AlShow, VLC and Media Player Classic - these suit almost all jobs - oh and even Irfanview too sometimes.

Reason I bring this up is - I shoot some vids on a model RC plane and finish up with a big AVI file. I usually use AlShow by default but was finding the image content either 'sticking' on first frame or playing a bit and then image freeze - with sound continuing.

I thought this was a dud file but then tried it in media Player Classic and with relief it played OK - and so was importable into my vid editing software.

So - this is a roundabout way of WONDERING how many players you may have tried, in case your default one is giving a problem, when another might be OK.I've tried Windows Media Player, Media Player Classic, Interactual, and powerdvd. I was surprised when Media Player Classic still had the jumpy picture, because it usually works for everything.Quote
