Well, I took the plunge and upgraded my Panasonic AE900 to a Sony Pearl. First off, :eek: this thing is gorgeous. I have a 136" Da-Lite Hi-Power screen (2.35:1 and 96" 16x9) and a dedicated theater.

I also have a Dell XPS Dual 3.2GHz with 2GB memory and 1.5TB of hard drive space. Running Zoomplayer with ffdshow and Avisynth limited sharpen MT. I used to have ffdshow scaled to 720p, then some noise reduction, then limited sharpen. Everything was smooth. Ran these settings on the Pearl and everything looked about the same only smoother and better from the Pearl upgrade.

Now I try to resize in ffdshow to 1920x1080 and I immediately get stuttering. Try to sharpen on top of that and it really grinds to a halt. Anyone out there with a 1080p setup? What are you doing? HDTV looks great through my ATI HDTV Wonder. DVD's look the same, but certainly no better as before. I was hoping to be able to crank it up some more.

Looks like it is on to HD-DVD and BluRay for me. Will keep the PC around for the DVD collection, but I can't come close to making this thing shine with regular DVD material. On the 720p projector it was really questionable whether I needed HD-DVD since we had made post processing a science. Now I think it is mandatory for me.

Any thoughts on getting more out of the PC? Besides wait for a new drive and Vista to be released!

read this thread and weep....

linky

i'm trying to figure out what to use in a 1080P sony wega RPT system, and it looks like i'm gonna have to get a fast duo core system if i want it to work (and that may be resize only). duo

my bad, need a duo core not dual core system..

Rule #1: You haven't wasted your money...you just haven't spent enough yet.
Rule #2: When in doubt...get both.
Rule #3: No need to invoke malice when stupidity alone suffices.

oh my....
Conroe is dual core.

There is Core Solo, Core Duo and Core 2 Duo, and coming next week Core 2 quad.

And yeah 1080p processing takes ALOT of horsepower.

I'm running FFDShow and resizing 3x, which makes it 2160x1440. CPU usage is between 48 and 53%.

Here are my settings:
  • MPC 6.4.9.0 (Output VMR9 Renderless, Use texture surfaces and render video in 3D)
  • Decoder: DScaler MPEG2 Video Decoder 0.0.8 (Output Color Space YV12, Do Analog Blanking Unchecked)
  • FFDShow-tryouts-rev135-core2duo.exe (Download here). Output YV12, Codecs: Raw Video -- All Supported. Resize: Multiply by x3 (Lanczos2, Luma Sharpen 0.9)
  • CPU & RAM: Intel Core2Duo X6600 and 2GB RAM
  • Video: Geforce 7900GS 256MB

No stuttering at all, picture looks great. Why do you want to run at 1080P specifically? Maybe 2x or 3x resizing would be better.

The Sony Pearl is a native 1920x1080 60fps projector. So I wanted to scale to that first and then filter. Will have to try your version of ffdshow and your settings though. What is the MPC piece?

Thanks!

Media player classic = MPC? From sourceforge?

Get a video card that supports all of the nVidia Purevideo features (7600GT or better) and ditch ffdshow. The newest nVidia drivers have a new control panel application that has a "noise reduction" and "sharpen" adjustments in the video section that works wonders on DVD video. It's run in hardware on the video card so it doesn't bog your processor down. The noise reduction really works well at removing noise without losing detail, and the sharpen does nice things without adding a bunch of artifacts to the image.

DVD playback on my HTPC has never been better. I'm only using a Athlon XP 2200+ and a nVidia 6600GT.

With the latest stuff the nVidia solution scores 123 on the HQV benchmark http://www.hardware.info/en-US/news/...es_123_in_HQV/
