Script Issues

While I gave my script to one of my lecture's to read over; one possible issue came up:
The screen scenes...There was worry about filming screens but I never really planed to record footage from the screen. I did however like the idea of using the glow of the television and showing it on his face.

Using camera techniques: shots and angles, I can show the character, the screen and the glow emitting from the screen without showing what is on the screen.

My original plan is to download files from YouTube and use those for the screen scenes in the film, like how I showed in my previous post On Screen but I would like to incorporate the idea of the glow from the screen.

Another possible issue that could come up is when the downloaded file is blown up on the cinema screen how it could be effected. The file was downloaded at 720p HD but I will have to experiment by playing the file on a bigger screen to see how it will look.
