Pretty much what the title says .. I downloaded a blu-ray movie from the internet and connected my 2.3/16GB RMBP via HDMI to my 46'' LCD Full HDTV to see it ..

However, while watching the movie I kept noticing that there was quite noticeable lag .. So, what is the problem here ?? My RMBP, my TV or my settings ??

If it doesn't lag in the media player, the problem is going to be with your wireless setup.

I'm having the same problem. Unfortunately, my projector is quite far from the wireless router. While it's not causing me any trouble when renting movies from the Apple TV, mirroring lags when playing video games or movies.

Is it pirated?

I streamed a 1080p concert from the staples center through my HDMI port to my 46" LCD... had an awesome time..

Through HDMI...? Sounds like it was downloaded, not streamed.
 
I wasn't using a wireless setup but a wired one (HDMI to HDMI) .. I made some more tests and I noticed that the lag is evident on my TV even when I'm not watching a video .. The scrolling speed of the mouse on the TV is not as fast as the one on the laptop's screen .. Any ideas on how to fix that ?? Is it possible that the problem may be attributed to my TV ?? It's a Samsung LCD TV from 2010 ..
 
Do issues exist when using the same cable with other devices? It's unlikely that there's an issue with your TV but the cable itself could be bad, I guess. Weird that the rMBP performs just fine but the image on the screen isn't fine.
 
I think it has something to do with the cable. I used an hdmi and i watched a 720p raid redemption yday with no problems. I also downloaded the batman begins in bluray and that also has no problems.
