I've recently bought a LED 47' Philips 47PFL5007G/78 and am trying to connect a Samsung S2 1TB External HDD with some videos on it.

But I figured out that navigating through the menus is extremely slow. It lags often, for long periods, making the experience frustrating.

On top of that, sometimes, after finally getting to the video you want, the top menu overlay "freezes" and doesn't hide throughout the whole video.

The External HDD is NTFS formatted and has about 700GB of files. The files are organized (as in not all just thrown in the HDD root), the have folders and subfolders.

Am I doing anything wrong or is it going to be always this awful to navigate?
