I have a 53' Panasonic hdtv. The specs>>
http://www4.shopping.com/xPO-Panasonic-PT-53WX54the tv being a bit outdated, doesn't have an hdmi port. Instead, it has a dvi port.
The port looks like this

We bought a samsung blue ray player a lil while ago which has an hdmi port so we were using component cables (blue green red) for the video. But recently my dad bought a hdmi-dvi cable off the internet and told me to hook it up. He bought a Hdmi-dvi-d cable
well... this exact one >>

So I hook it up, go through the settings on my bdplayer, turn on hdmi and so on, but nothing works; the 'digital in' screen is blank regardless. The resolution on the bdplayer was set to 1080i so I played around with it and somehow it started working on 480p. Even on 480p though, the whole screen shakes from time to time. If I change the resolution to anything higher (720p 1080i 1080p are my options) on my bdplayer, the 'digital in' screen on my tv goes blank and I have to revert to "video 1" just to see what im doing again (yellow red white).
After this all happened I started reading both electronics' manuals to figure out if I was doing anything wrong. It didn't give me a clue. So I researched a little and found out that there are different types of DVI's, such as I, D,A.
Also I found out that there are 2 different types of DVI-D's. the single link and dual links. Judging by the pins I would say that I have the single link. So I figured that was the problem, and started to look online for a HDMI-DVI-D dual link cable, and turns out it either doesn't exist or is very hard to find.
The specs for the cable I bought says "Supports the following resolutions: 720i, 720p, 1080i, 1080p, 1280x1024, and beyond (WITHOUT the need of a booster)"
My tv, well on the far right corner it says 1080i , BBE. So I should at least be able to go to 720 right? I dont know what that BBE is. When I go into the setup of the tv, theres no sign of HD settings. Theres video, audio, parental lock, settings. The video is all about the picture, colour etc, even the advanced settings show nothing about hd. Settings has random crap like cc off/on etc.
I made sure too that both ends of the cable were securely placed. I've been at it trying to fix this problem for a couple of hours now

Do I have the wrong cable? Wrong DVI format? Is there some setting im missing? Any help would be greatly appreciated!!
