I have saved some programmes onto a flash stick and transferred into a video folder on my PC. Does anybody know what software i require to record to dvd from my PC?

I use Nero, a tad expensive, you may find a cheaper option.

You should find a dvd maker bundled in with the windows stuff look in all programs..
