just wondering?? it would let voom know who are hdtver's only and which are not plus if it were all out hdtver's then obviously voom may entirely switch to hdtv force sd'ers to see everything with bars at bottom and top. it would also help reduce the $50 price of voom to probably $30 and maybe the vavavoom extra $40 to maybe $25 (hdtv channels only not the extra sd channels).
