Upscaling software for HTPC

[Joe]

Given there are upscaling DVD players available, is there any DVD playback
software one could run on a HTPC that would essentially offer the same
capability?

Every DVD player application on a HTPC that I have ever seen upscales
to the resolution of the HTPC.

I currently run my HTPC at 1440 x 816 at 75Hz, and the DVD player that
I use updscales to it just fine.

I dont beleive this to be the case. Ive checked Power DVD, Theatertek and
they both report a DVD is running at 720x576 even though my desktop res is
1280x720. I have since become aware of FFDShow filters which can be accessed
from Theatertek and which does post processing resize function to perform an
upscale. Just experimenting with it now.

As John said, all players seemlessly scale the DVD to your desktop's size.
If they didn't you'd have a little window inside your desktop even when you
picked fullscreen. I use powerdvd to send 1368x768 to my projector.
Windvd, zoomplayer, etc all work too.

Joe,

720x576 is the native resolution of the DVD, but the player is indeed
scaling it up to the resolution of your desktop. if you have decent
monitor or projector, then it will tell you what resolution it is
currently displaying, so you can see for yourself.

BTW, I run Theatertek in my HT. If you check the aspect ratio editor
(ctrl+E), it will tell you the output resolution

Ok I see what you are saying. So what is the point of FFDShow's rescale
function then?. read this article at this website which shows how to setup
FFDShow to upscale a DVD to near HDTV like an upscaling DVD player does.
They use it from within Theatertek and point to before and after differences
in which by postprocessing with a resize function using Lanczos algorithms
there is more detail revelead in the "upscaled" picture.. Im not sure I
understand why they would bother with this tutorial ??

Joe,

In most cases, the actual resizing is handled by the video card itself
in hardware. Take a look in Theatertek for a config option called
"DXVA". If it is checked, then the video card is doing the resize, if
not, it will be done in software. Check the CPU utilisation both ways
to see for yourself the difference it makes to the CPU load.

FFDShow is a pretty clever, multipurpose filter that sits between the
DVD player application, and the video card. FFDShow can do lots of
filtering to the video stream, such as noise reduction, sharpening
etc. One of the other things it can do is resizing of the picture,
using many different algorithms, which are supposedly better for video
than the resizing done on the video card. It does so at the cost of
much increased CPU usage.

Try it for yourself and see what difference it makes on your system.

Regards

John

14 inches is 2 more that you need for that true HT experience :-)

Thanks for the wishes mate, Merry Christmas to you too

Every software DVD player does this when you switch to fullscreen mode.
