I need to buy a HDMI to Audio Video converter to enable connection between my laptop and old generation analogue TV. Where can I buy this converter in New Delhi or NCR?

The playstation is connected in the back with hdmi and i can see and hear everything.

Now my pc is a very big i can't take it to the living room but i want somehow to record to something my ps3 gameplay so i can move it later to the pc.

Is there any external hard disk or something that i put hard disk inside and it will be connected to the back of the tv and record the video ?

I am using TOSHIBA REGZA TV set.
