Broken Video Checker

Pay for this project is $30. I need a program which will perform a very simple function. Basically, it will take a text input file ( let's call it "[login to view URL]"), and scan each URL and determine if the video found in the URL is broken or not. The URL's will only contain videos found on [login to view URL], and I only require that it be able to determine if videos are not working based on if the page the URL leads to shows an error message or not. Here is an example of the URL I am talking about: [login to view URL] At first glance, the video appears working. However, once you press play on the video, an error message appears and the video cannot be played. What I need is a program which will look just for this specific error message from each URL it checks. The difficulty in this project lies in the fact that this message does not appear unless you press "play" on the video. Everything else regarding this project is very straightforward: Program reads "[login to view URL]", and after determining broken links, will produce them in "[login to view URL]" Program will be run on Windows 7 Home Premium. Additionally, on [login to view URL], it is required that comments be allowed on each line after the URL (this will allow me to distinguish between each video). Each line on [login to view URL] will have the URL, followed by a space which signifies the beggining of comments for that line, and then the actual comment. In is important to make sure that in "[login to view URL]" , the entire line is produced when a video is determined broken (including the comments). Here is an example of a working video for smotri: [login to view URL] I look forward to working with anyone who can accomplish this Thanks for your time.
