I love putting old '90 music and videos on the TVs but right now the flat screen TVs isn't looking too good for these kind of videos.

Is it possible for CRTs to be added in the future? Perhaps putting them as 4:3 scaling for the best experience?

is on my plans, i made the box_tv as a minecraft-like television, not as a CRTs television. so, will be added. probably in the 2.2.0
