I bought a movie on itunes and it will not play even after re-downloading it.

I bought a movie on itunes, it would not play. I contacted apple support people, and they told me to delete and re download it, I did that and it still will not play, I don't know if I'm doing something wrong or if my itunes isn't up to date, or maybe it's because I'm not trying to play it on an apple device. Whatever the case me be, I just really want to watch this movie, or get a refund.

You should be able to play films on windows computers, if it wasn't compatible with it (e.g. you should have got an error if you tried to buy an HD film on non-HD compatible computer).
The current version of iTunes is 11.4 - you can see if there are any updates available via the Help > Check For Updates menu option.
Or you can download the current version of iTunes from here : http://www.apple.com/itunes/download/
What happens when you try to play the film, and do other videos that you have in your iTunes play ok ?
If you can't get it to play but other videos play ok then contact iTunes Support (these are user-to-user forums) : http://reportaproblem.apple.com

You Tube will not play in Safari 3.0.4

I am not able to watch You Tube videos in their entirety 95% of the time. Occasionally, I have been able to view a complete video, but most of the time I can only watch 5-10 seconds before the video stops. I have tried emptying the cache, but this makes no difference. I have had this problem with 3 different ISP's, so that does not seem to be the problem either. I have a decent DSL connection right now. Is this common, or is anyone else able to consistently view You Tube without any problems?

Ah, alright. Not as dire as it could be then. For starers, try quitting Safari and trashing the contents of your cache folder, ~/Library/Caches/Safari/. Also, if you're not particularly attached to browser history, also trash the file, ~/Library/Safari/History.plist.

Non retina 15" MBP will not wake up after sleep following mountain lion upgrade

I have an early 2012 15" 2.2 MBP with the 4gb video card. since upgrading to ML a lengthy sleep renders it unresponsive. it will not wake up and will have to be force shut down, then restarted to use. you can here the hard drive spin up after a long sleep (6-8 hours) but only after you hit the power button. even so it's completely unresponsive until restarted.. i noticed apple released an update for retina MBPs for the same issue. unfortunately they have not released the same update for non retina users yet.

Since you had NO problems before ML upgrade:
Not to side with the tech or you, because upgrading OS can be frustrating (it shouldn't).
It appears that you need to do a reinstall (backup first). Its pretty simple to reinstall, just go to boot drive and reinstall. You'll probably have to reinstall print drivers, other than that it's pretty straight forward.
A couple of things I'd do before and after reinstall is to repair the disk (3 times each) while in the boot drive. Then once completed choose the startup disk in system preferences or at least verify it's the startup disk, then repair permissions. If you add apps or printer drivers repair permissions again.
A major problem for lots of folks updating to a new OS is they don't think about disk health....And that's why it's important to insure everything is in mint condition before upgrading to a new OS. The same reason many choose to do a FRESH install of a new OS, by zeroing out the HDD (or SSD) and then repairing the disk and then installing the new OS (you MUST have a solid backup before doing so).
I always have at least 2 solid backups before doing so, but that's me. 100% of the time I do a fresh install of a new OS.
I have a spare computer I use as a test machine for a week or so by upgrading without fresh install. After figuring out all the possible bugs with the test machine I do a clean install of my other computers and once there stable I do a fresh install of the upgraded one.
Not a lecture on how to do things just my procedure which has served me over the years without any problems.
I have photos, videos, documents, and financial records dating back to 1991 so I must be doing something right.

My iPad will not play sounds on certain applications. ie: if I click on a video from FB sound will not play. If I go to YouTube and play the same video sound will play. Also certain games will no longer play sounds. They always played sounds but now won't now. I just went to my churches web site to watch live service and again no sound. I grabbed my dads iPad and the sound works fine.

If you lose sounds for keyboard clicks, games or other apps, email notifications and other notifications, system sounds may have been muted.
System sounds can be muted and controlled two different ways. The screen lock rotation can be controlled in the same manner as well.
Settings>General>Use Side Switch to: Mute System sounds. If this option is selected, the switch on the side of the iPad above the volume rocker will mute system sounds.
If you choose Lock Screen Rotation, then the switch locks the screen. If the screen is locked, you will see a lock icon in the upper right corner next to the battery indicator gauge.
If you have the side switch set to lock screen rotation then the system sound control is in the task bar. Double tap the home button and in the task bar at the bottom, swipe all the way to the right. The speaker icon is all the way to the left. Tap on it and system sounds will return.
If you have the side switch set to mute system sounds, then the screen lock rotation can be accessed via the task bar in the same manner as described above.
This support article from Apple explains how the side switch works.

I've restarted my iPad, there are no available updates that I am aware of.

Try reset iPad
Hold down the Sleep/Wake button and the Home button at the same time for at least ten seconds, until the Apple logo appears

Can anyone tell me how to restore my itunes library and playlists? After I downloaded mountain lion my library is missing and my devices can be synced to only one library ...the missing one

can anyone tell me how to restore my itunes library and playlists? After I downloaded mountain lion my library is missing and my devices can be synced to only one library ...the missing one

That .itl file actually is the library -- at least the critical part of it although the library is actually many files and folders.
Try starting iTunes and immediately hold down the option key. When it asks, guide it to the .itl file.
It's really hard to say without being able to poke around your computer. Upgrading should not delete the old library, but still it happens to the very, very few which is why we make backups before updating. If the old library file is gone then so are your playlists. You can always see if the following is of any use:

Why does my mouse make blank spaces on my screen as I move it? It started happening after I downloaded Mountain Lion

Why does my mouse sometimes cause my screen to erase as I move it? It started to happen after I downloaded Mountain Lion.

You could try booting into Safe Mode to see if it fixes the problem. To get out of Safe Mode, restart as usual.
