Watching Movies From Laptop to Plasma Television

I have a XP Gateway laptop and plan to use its wireless connection to connect to my Vista home desktop network to watch movies, pictures and listen to music, on my samsung plasma PN42A45P1Dx2A television.
I understand that a DVI port would be the best, but the laptop doesn't have it, only a D-Sub port. I have read via internet that the D-Sub ports, do not provide a very good picture.
So, my question are
1)Do I need to purchase another piece of equiment to stream video to the television? OR
2) If avaliable, purchase a D-SUB to HDMI cable?
Thanks so much

Re: VGA to HDMI

In reply to: Watching Movies From Laptop to Plasma Television

You might like to spend $475 on a device like http://www.vpi.us/hdmi-scaler.html
But it isn't wireless.
http://sewelldirect.com/VGA-to-HDTV-Converter.asp is much cheaper, but not wireless either.
A device like http://www.smarthome.com/7743B.html is cheaper and wireless, but it isn't HD, so the picture wouldn't look as good as you want and probably be unacceptable for you.
I'm afraid wireless HD isn't available at the moment.

Three notes:
1. I wouldn't buy anything before I had seen the picture quality myself. That means visiting a shop and looking at a demo, not buying via Internet.
2. A week ago I turned up to other devices and a link to an interesting discussion for another member. So please also see http://forums.cnet.com/5208-7587_102-0.html?forumID=69&threadID=302106&messageID=2817226#2817226
3. You might like to read through our recent community newsletter discussion about "Using PC as part of a home entertainment center": http://forums.cnet.com/5208-10149_102-0.html?forumID=7&threadID=301619&messageID=2814353. It might contain useful hints for you.

Well, two questions lead to more questions.
After reading http://forums.afterdawn.com/thread_view.cfm/310199 I am confused some what.
So some questions
1) VGA sends an analog signal,,correct?
2) Since my tv is able to recieve air analog, its safe to say that it can recieve analog from a cable,,,correct?
3) Due to having HDMI to DVI cable already, I purchased a DVI-A to VGA adapter. I shouldn't make a difference if the DVI adapter is DVI-A instead of DVI-D,,,correct?

Here is link to the tv purchased, if specs are needed,
http://www.samsung.com/us/consumer/detail/detail.do?group=televisions&type=televisions&subtype=plasmatv&model_cd=PN42A450P1DXZA

Anyway, VGA connection from computer to DVI-A adapter, to HDMI input on TV isn't working.
