I was at walmart tonight and in their clearance section they had a RCA 9' digital optical cable (model DT9HP) for 9 dollars and it was regularly 23 dollars. I decided I couldn't pass the deal up, if anything I'll just take them back if they aren't any good. Another question is.... I know ill hook up my dvd player's audio with the digital optical but would i also hook my tv's audio with a digital optical cable into the reciever? Finally does anyone know if a regular digital optical cable will work with the xbox's HD pack? or is it a special cable?
