I was used sun direct HD for 6 months,
HD picture clarity and HD audio quality very good. SD picture and audio wise, all sun group channels very good, and leading channels also good and some free channels like puthiya thalaimurai, 9xm, zoom, capten news, Sony mix picture quality is poor like 240p in YouTube. Then i moved to tata sky, i feels very good SD picture and SD audio quality but HD picture and HD audio clarity little lesser than sun direct, feels more base.
