I am Samsung LCD Tv, I want Home Cinema Theater. I prefer Samsung Cinema Theater H/T C450 of Rs. 19,500 as it has optical input which will enable me to play movies using USB and still will hear true 5.1. Sony has input optical but prices are more than Rs. 34,000. Home Cinema Theater do play movies using USB only simple and 2 format only. So, buying Samsung will be good. BUT NO Samsung dealer provide warranty of Home Cinema Theater. Please give suggestion.
