Well i suggest you yo get the 46HX925 its the best lcd out there ,definitely the best 46" tv in india.
You can always buy a good external media player for less then 5k,but a tv is usually going to stay in your house for around 5 years to 10years,so with that kind of budget i would give performance the primary criteria.
The HX925 also comes with a strong Gorilla glass.
