I'm about to take delivery of a Panasonic Projector AE700 and I'd like to hook it up to use my computer as a HTPC.


I want to use Powerstrip and DScaler and FFDShow to upscale and pixel to pixel map DVD's to 1280 by 720p.


My PC is a Pentium 4, at 1.5 GHZ with 640MB Ram, Radeon 9800 Pro, Pioneer DVD player and running Windows XP Professional.


I am concerned that the PC will not have enough power to feed a stable signal to the projector.


I would hate to hook the whole thing up and end up with a jerky images because the PC can't handle the processing.


I recently down loaded Windows Media 10 HD files in 1280 by 720p and some played okay but others were unstable.


Are my fears justifued and should I go out an buy a Denon 2910 or is the HTPC route worth pursuing?

I suspect you'll need more CPU power.

For DVD playback your computer should be fine. You don't need powerstrip or Dscaler for DVD playback. FFDShow may be iffy, chances are you will need a faster CPU to take advantage of FFDShow. However, you may not need it. Try Theatertek 2, I find the picture quality amazing even without FFDshow, and it uses ~30-35% CPU on my 2.4Ghz P4.


Radeon 9800 will support 1280x720 natively.

Thank you all for your advice and expertise.


Olyar 15.. you say the Radeon 9800 Pro supports 1280 by 720 natively but I don't see this as an option under the choices for resolution.


I suspect from what I have been reading on the forum that I will need Powerstrip in order to choose a custom resolution like 1280 by 720.

Is this correct or am of way of base ?


Also... if I use powerstrip to map a DVD to 1280 to 720 pixels... then why would I need to use DScaler aswell ?


Are they working together to create an upscaled 1280 by 720 image or can I just use powerstrip on its own ?


What is the best option?

Your choice of resolution may be limited by what the video card detects the monitor to be. For example, I have my Radeon card hooked up to a Samsung DLP rear projector that has a 1280x720 native display. The drivers only offer me a choice of 800x600 and 1280x720 resolutions. Assuming that your diplay has a native resolution of 1280x720 (and is able to communicate that fact to the video card) then you shouldn't have a problem. If not, then you will have to use Powerstrip to force that resolution.


Dscaler is mainly used to upscale and deinterlace input from a TV capture card. It is not used for DVD.

It's common plactic to use the Sony GDM-W900 monitor drivers. This allows many resolutions to be available.


You need to manually force the Sony driver install. Don't allow windows to automatically select/search for anything. Select the driver from a list.
