and an S-video cable. I bought it because I thought I could use my TV as a big monitor but the quality is awful (compared to what I wanted). It’s great for watching dvds and videos though because those actually show up really well
Keep an eye on displayport. This is a new digital interface that is likely to be adopted by computer monitors first in the following couple years but is likely to be a standard across both computer monitors and high def televsions within the next 5 years.
For now follow robmandu’s advice. Typically S-Video is better than composite although they both have the same bandwidth. S-Video will typically give you better lines. If you are transferring your video to a larger screen I would go with S-Vid but if you are transferring onto a smaller screen composite is likely cheaper and you probably won’t see a difference.
