I have purchased several commander in chief tv shows using iTunes but,
how can i burn these onto a DVD so I can play it throgh my TV? I will
tip if I get a quick good answer.

According to Apple, it's not possible.

How do I burn my purchased videos to CD or DVD?
You can burn back up copies of iTunes videos to a data CD or DVD.
However, you cannot burn iTunes videos to a DVD for playback on your
home entertainment DVD player.

Can I use my purchased videos in other applications?
Videos purchased from the iTunes Music Store cannot be opened in other
applications, such as iDVD or iMovie. Purchased videos are for
personal use only and are best enjoyed on the new iPod.

I hope that helps.

Thank you so much for your quick comment, I am very disappointed I
thought I could do it, oh well. I'll have to watch them on my iPod i
guess. Thank you!

Google video (i think) you can burn to DVD.
