Help with displaying PC on TV via DVI/HDMI

Okay, here's the details:
I have a laptop, which I use to display videos on my HDTV (Samsung Series 6) through a D-Sub/D-Sub (standard monitor cable).
Problem is, this cable displays only up to 1280x1024 (or 1024x768, but nothing else). So, I bought a DVI/HDMI cable to display high resolutions on my tv. Then, I realized my laptop didn't have a DVI output.
I got my Desktop to test it, and it displayed at 1920x1080, everything worked perfectly.
On the next day I bought a DVI/D-Sub adapter (Female DVI/Male D-Sub), and connected everything to my laptop.

But then I can't get my laptop to display anything on my tv! It just displays "No Signal", and the computer unchecks the "Extend my desktop to this monitor" automatically.
Is this a HDCP issue?
Well, here are my Laptop Specs, should they help.
