How to change default media player setting in Mountain Lion

You need to do what you are doing with a file, not the application. Select a file of the type you wish to change and Get Info. Then choose the application you wish to use to open that file. If you want it to open all files of that type, click Change All.

you need to find the file you are trying to have open with a specific application.

for example, I'm going to use an MP4 file titled cat_adventure video.

here it is in finder

I right click (secondary click) it in finder, and then hold down the option key on my keyboard.

the Open With dialogue should change to "Always Open With" and then you choose your application from the pull out menu when you hover that.

You can make it so all MP4 or whichever file you are using (AVI, MKV, etc) to open with a specific app by right clicking the file choosing get info

The difference here is I'm not selecting the application but a file with the extension of the video format I always want to be opened with a specific application

once in the get info menu I can then select to have the video always open with a certain app.

1.click the open with accordion menu arrow if it is pointing to the left. it should be pointing down.

2.select the application you want to always be associated with that file format

3.select Change All to have that file format always be opened with that Application.

Where this isn't working for you is because you are doing this to the Application itself. you don't do it like that. You need to find the type of file you are trying to open with itunes and then go through these steps.

selecting the application (itunes) instead of the file (mp4, avi, mkv, flv) will not allow you to set what the file format lets you use to play your video.

having said that, itunes is very limited in what it can and can't play. Mainly .mov and mp4's (apples proprietary extensions)

Actually, watching streaming content on the website itself is usually the best practice for me, because I can choose to view it in HD or none HD depending on my connection.

I think the issue you are facing here, is either your video card, but it is most likely your Internet Service Provider.

I would call them and request to be upgraded.

Depending on how long you've been with them, you could have some leverage in getting them to bring your rate down. but that's up to you.

This could also be due to other people who are using your internet connection. Sometimes, if someone else is downloading a large file or if someone is also using the same Modem connection you are using, your internet will be bugged down, because it is downloading and uploading to their's and your computer, and it will sometimes clog things up.

I use VLC to watch some of the films I backed up.

I've not had a good expereince with using Quicktime to play some of my backed up movies, even with perian installed. You will not be able to play some file formats without Perian, since that is the plugin that is supposed to unlock Quicktime to work with all media (I have yet to see that)

I never have watched a youtube video on VLC but I have watched some ShoutCast TV stuff which usually loads fine, given my internet connection is at full speed.

But in a nutshell it's your internet connection, and you either need to call your ISP or see if anyone in your residence is using your internet. If you have a wifi connection, make sure it is locked with a secure WPA2 encryption that only you know. Sometimes, if neighbors are close enough, they can use your internet with out you being the wiser.

Thank you for letting me help you today, you have been very responsive and I appreciate that. You are better at using this forum then some people I have seen on here.
