Hi there drlew1!
I love watching videos, especially on my computer! I will be delighted to provide you some additional information.
You will want to transfer your videos to your computer first. You can send the videos to an email and save them or plug your phone in to your computer with a USB and drag/drop most of the time.
Once you have them transfered you can use video players such as Quicktime or Windows Media Player to view.
Which phone model do you have?
What type of computer do you have?

If you're referring to Verizon's PIX FLIX web site, log into your on-line MyVerizon account, then at the top where it says MyVerizon, hover over that until you get a pop-up menu. Select 'View All' under My Messaging. Scroll toward the bottom and click the red Manage Your Album button. Hopefully, your photos and other files are there.
