QT pro 7 edits not working

I saved my .mpeg movie to .mov, then made a selection to shorten my movie, but the edit options and trim to selection options are not highlighting and I cannot edit. Anyone have any advice on this? I saved as .mov by doing a "save as" quicktime movie and it indicates the file is now .mov.

All you've done is place the MPEG-1 file inside a .mov container.
QuickTime Pro can't edit muxed file formats (MPEG 1 or 2 and Flash) and can only export the video portion of the file.
MPEG Streamclip (free) can edit your MPEG-1 files.

The sound on my macbook pro is not working

The sound on my macbook pro is not working. When I increase the sound, the icon appears as if everything is working, but no sound comes from the speakers. Earphones don't work either. I have tried a PRAM reset but at times, this doesn't even work. It's really frustrating having to restart my computer every time I want the sound to work, and even when I do that, theres a 50 50 chance of it working again. It generally happens after my laptop goes to sleep and I wake it up. Has anyone else had this problem and fixed it or even know what caused it?
There are a lot of discussions around the earphone jack but I have checked that. I've tried a PRAM reset which hasn't worked, and my sound output is set to Internal speakers.
HELP!!

Hopefully one of these steps should solve the problem.
1. System Preference > Sound > Output > Internal Speakers
    Highlight Internal Speakers / Headphones
    Make sure Mute is not enabled.
2. Remove the headphone.
    If you see red light in the headphone port, plug the headphone
    in and out of the port 5 or 6 times to flip the microswitch inside.
    Sound output may be stuck in the digital mode.
3. Reset SMC.     http://support.apple.com/kb/HT3964
    Choose the method for:
    "Resetting SMC on portables with a battery you should not remove on your own".
4. Applications > Utilities > Audio MIDI Setup
    Audio Devices window
    Side Bar
    Click the Built-in Output.
    Under Mute any of the boxes checked? If so, uncheck it.

Macbook pro sound not working

It seems that the sound on my macbook pro does not work when watching videos such as those on youtube. Please help.

Here is YouTube's help page if you have no sound on YouTube videos:

Try re-installing Flash player. I'm assuming at this stage that all your other audio works fine, e.g. CDs, DVDs, system sounds, etc...

Don't use any cleaning spray. Wipe with a moist but not wet microfiber cloth.

Output volume on my MacBook Pro is not working

My output volume on my MacBook Pro is not working. When I go to "Settings", then "Sounds", then "Output", I can not slide the volume bar at all, or change it in the menu bar?

See if a PRAM reset will solve the problem;

Yuu can try to reactivate your iSight camera by opening up iMessage.. navigate to Preferences/Audio Video,and then click on Camera. IT shoudl be grayed-out if you only have one camera hooked up to your machine. If you have an external camera, then disconnect it from your machine.

My charger for my MacBook Pro is not working

The charger cord for my MacBook Pro is not working. This happened before but I do not remember what the tech guy had me do. It was a simple fix....

If the SMC reset does not work check for contamination or stuck pins:

Hello Betty7,
Please let me take a moment to say "Welcome" to the HP Forums.
I hope you enjoy your experience!
I see that you are having an issue with getting the printer reinstalled.
I suggest that we start off by running the HP Print and Scan Doctor. If the Doctor fails, please let me know where it fails as well as any error codes it may generate.
Thank you for your time.

I am using Acrobat Pro XI not working at all in Windows7 64bit - tried everything. About a month ago I built new computer. Acrobat worked fine. In last week it started not producing PDFs using Save As and would crash when processing scanned document. So I redownloaded exe file, used the acrocleaner to erase existing program, and reloaded Acrobat Pro XI.
No the program will not start at all. Freezes when opening by clicking PDF file or by opening program icon.

Hi - I have the exact same model as your MacBook and had a few questions as mine is acting up. I upgraded the ram to 8gb (2x 4GB ram) and ever since then my computer has not been running as smoothly and the start up time is horrendous. Have you encountered this problem? And if so how did you fix? What would you advise me do?
I was thinking of reverting back to the original factory 4GB then rebooting the entire computer. Any suggestions?
Thanks in advance!

Merge to HDR Pro does not work in Photoshop 14.2.1. Image appears black. What is the problem?

Attached is screen shot. What happens is I go to File/Automate/Merge to HDR Pro, then select my 3 images, which are flattened psd files (I have tried tifs and jogs too), hit OK, it processes them, but instead of the image appearing, I get this black image. You can see my original images at bottom... jpegs too),
