Quick Time streaming: only sound

Open the HD/Library/Internet Plug-Ins folder and drag the QuickTime Plugin. webplugin to your Desktop.
Quit and relaunch Safari and try the page again.

Delete it. It's used by some Dashboard Widgets and a newer one will be installed after your next QuickTime update. That one will probably work.

I am actually having the opposite problem. Ever since I bought the $20 component in order to convert my video files, I can only see my videos, I don't get any sound. Help!

ha ha and i'm having the opposite problem of that - i can only get sound!!

It worked. THanks. QT was playing only sound, no picture. Removing the QuickTime Plugin.webplugin did it.

I have a program called Tubesock that lets you convert YouTube videos to .mp4 files that I save on my hard drive and that I use to play using Quicktime. So to make it clear, these are not streaming files but are actually converted on my hard drive. I have done this many, many times until I just got the 7.4 update and I can no longer see the video, just hear the sound. Is there a fix or can I downgrade to 7.3 or what because that was an extremely useful tool.

Thanks, QuickTimeKirk, your technique worked for me, today, 1/28/08. Funny that something so utilitarian and efficient as your few steps couldn't be posted in the QT FAQ. Looking at this thread it's clear that other Apple users have had this kind of problem. Thanks, again, it worked for me.

By the way, after just upgrading to OS 10.4.11, it took a number of failures with iSync, a number of forum prowls to find another link, valuable as this one, reminding users to run DiskUtility to verify/repair permissions and volumes. That also helped me finally be able to run iSync successfully.

Having the same issue as BossHoggBrowner. Only SOME videos are affected, though.

I am also having the same problem as stated.
I converted a TiVo recording to MPEG-2. Updated to QT 7.4.1 and purchased the MPEG-2 Playback component. When I play the video in QT, you hear the sound but no video, all white.

I want to downgrade to an older version of QT but unable to. Anyone found a solution?

I have same problem. Sound but no video. Some videos previously converted with Tubesock play fine. Recently saved Tubesock will not play video via QT or through using the remote Movie viewer. They do play when using iTunes.

HELP! i cannot get any movies to play with video... only sound. Please let me know what the dealio is. I am running XP and have very little (none) knowledge about any Mac software except of course itunes. This is driving me nutz! Thank you for your help in advance!

Hi all,
I upgraded to QT 7.4.1 (and I have Pro too) and wish I hadn't.
The problem I had was my Tube Sock program wouldn't show video in QT only the audio came through. They would however play in ITunes.
I tried some of the suggestions I found here and no luck.
I finally went back to Tube Sock and downloaded the old version 1.0.1. and now I can save You Tube videos with sound and picture and they open with QTime too.
I emailed stinkbot the tube sock people but haven't heard back from them yet. The newer 2.0 version was cooler but hey I got sound and video so I will put up with the barber shop pole until someone gets this figured out for us.

I came across another thread might be useful. It helped with my formerly video, then audio-only, movie files. The gist of it: change .mp4 to .3gp
