yes.. i use to do it that way nung... big screen tvs did not yet have vga..
ngayon di na yata sulit gawin..
problems
1) malabo.. hindi mabasa yung text dahil mababa resolution ng regular crt televisions
2) cost of converter.. i bought mine in china for mga 2k+
3) usual tvs ngayon meron na kasi vga in.. and hindi na super mahal big tvs ngayon..
