Home Theater for under 25k

[Chaos]

My parents need some new speakers for their TV. They want a simple plug and play system which will be mostly used for DTH and the occasional movie or music album. The TV supports HDMI ARC so i'm assuming a 5.1 home theater which has HDMI ARC should serve the purpose of not having to use 2 remotes, one for the TV and one for the speaker.

I know you guys wouldn't recommend going with a 5.1 home theater from one of the electronic biggies but they don't seem too keen on investing in an AVR and then add speakers etc. I've shortlisted the following models. Which one would you guys recommend?

1. SONY HT-IV300 Home Theatre System
