Effective resolution of camcorder's sensor - does it really matter?

Let's see,

The full HD Sony HDR CX-210 has a sensor of 1.3 megapixels effective resolution. To make the video footage full HD (2 megapixels,) the camera interpolates the 1.3 megapixels into 2 megapixels, thus making the picture fuzzy and it looks over-processed.

Now, the full HD Sony HDR CX-220 (which is cheaper than the 210,) has a sensor of 2.2 megapixels effective resolution. So it doesn't have to interpolate to make the footage full HD, and we expect the footage to be much sharper than the CX-210.

But, reviews say that CX-220's picture quality is much worse than the CX-210. Some say the 220's footages are very un-sharp. Why is this? The sensor produces more pixels than a full HD resolution.

Could you please explain?

Thank you.

"effective resolution" is after it has been processed or upscaled to a higher resolution. The sensor is probably at best 720x480 then it is processed up to 1280x720 or 1920x1080 causing the distorted image.

Really? So it uses SD sensors to produce video in HD format, not resolution? Then what's the use of selling these cameras at 20,000 INR when an SD camera can be had for just 5000 INR? Marketing, eh?
