New Nvdvd decoders WOW! - Page 2

Note to all you other people out there with *COUGH* another version *COUGH* of nVDVD 4 installed, make sure you uninstall it and delete the NVIDIA Corporation directory before you install this, otherwise it just updates the filters, not a full install.

I never had any previous version of NVDVD decoders installed. I purchased the official version released today but I'm having two problems.

1) Same audio problem that others are having.

2) Initially, the video was full screen. But a little later it shrunk with black borders all the way around. If I restart Sage, it returns to full screen; at least for a while.

Anyone having these same issues and determine a solution?

P.S. As far as picture goes, I guess it's ok. I really don't see all that much of a difference (if any) coming from the Cinemaster codec.

hmmm... "Sorry, the NVIDIA DVD Decoder you are trying to add to your cart is currently unavailable."

Oh well...

It works for me (I bought it last night) and I tried it again and it works now too.

I've been using these in Sage since TT2.0 came out. They do look slightly sharper than the whatever ancient version of Nvdvd I was using before but its not really a massive improvement or anything. I think part of the problem for me is the original source (dish network) isn't super high quality to begin with. But I'm happy with it now and its definitely better than what I was using previously. I'm using VMR9 as the renderer, on a 9800pro.

Although before you buy, note the fine print:
-edit

Word at AVS (from actual users) is that it works fine in other apps, it's just the DD/DTS decoding only work in the apps listed. Probably a liscensing/certification thing. Oh, and VPP is included as well apparently.

-edit2

The official word on application support:

Stranger89, or anyone that may know, I have heard that there is software and a hardware VPP and that the hardware VPP only works with certain Nvidia cards. Does anyone know which cards the hardware VPP works for?

From what I've read, only the 6x00 series cards support hardware VPP. I've also read that the 6800 series has some problems with hardware VPP.

stanger89 · #31 10-21-2004, 03:47 PM

My understanding is that the HW VPP works on the DX9 hardware, so that means 5 and 6 series cards.

As for the VPP, this is getting kind of confusing, too many acronyms flying around, good thing I'm an engineer

... or is it

Anyway, I believe there are two things to consider the VPP which is basically a film-detection filter (it aids deinterlacing so improperly flagged film material can be properly reconstructed). There are two ways the VPP can be uses, in software (via the nvpp.ax filter) and in hardware, by running the standard nVDVD decoder in DXVA mode. To the best of my knowledge, DXVA isn't broken...

I just checked and with nVDVD 4, the 61.22 drivers, and a Geforce 6800, on an AthlonXP 1800+ I get ~60% CPU usage (burst to about 80%) in software mode, when I set the decoder to DXVA, CPU usage is ~30%. So yes DXVA does work.

What is broken apparently is the VPU, which is the programmable video processor. What it does is WM9 decoding, video encoding assist.

Thank you for your email. Only the Geforce 6 family (Geforce 6200, 6600 and 6800 family) features a programable video processor. Next month, we will be releasing software which will take advantage of these features.

I have several questions mainly because I am getting a new FX 5900XT and I got the new NVDVD 4.00.58 decoder. I am using the official 4.00.58 nvidia dvd decoder.

1. In Sage I can set the Video Decoder to two different Nvidia options. 1 being Nvidia Video Decoder and the 2nd being Nvidia Video Post Processing. Which one would be best for my card?

2. There is DXVA MPEG Mode. There is Mode A-D. What are these and any idea what I should set them too for my new card?

3. There is DXVA Deinterlacing. What does this do and what would be the best setting for me?

Thanks

That depends, if you're running in DXVA mode you'll want to use Nvidia Video Decoder (and set De-Interlace control to smart in the decoder properties). If you're running in software mode, I'd try both, but the Nvidia Video Post Processing (SIC) is the one you probably want.

Leave these as default, MPEG Mode will probably do you no good even if you change it, and likewise with the Deinterlacing.

Thanks for the info.

I went out on a limb and bought this decoder yesterday as I've been somewhat underwhelmed by the quality of my recordings. All I can say is, wow! The $19.95 was well worth it!

You could fill a thimble with the knowledge I have about decoders and this whole PVR thing so everything I have is un-tweaked and bog standard. For a pretty much install it and go configuration, this new decoder works great!

My exhuberance is based on the purely non-technical opinion:
Previous setup: video still looked like MPEG - that is to say, it very much looked like a computer had recorded it and it wasn't close to the quality of the original signal
nVidia decoder setup: how is it possible that it looks BETTER than the original, analog signal? This is done by my highly subjective test of switching inputs rapidly between computer and straight analog cable on the TV.

I've used the nVidia setup for a couple of recordings and haven't noticed any problems with tearing, audio-sync or anything else. It just works and wonderfully at that.

(As a note, it is very possible that my raving of the nVidia decoder is influenced by just spending $20 on it and it better be worth it!

So I purchased the offical decoders from NVidia. Unfortunately it's still not letting me access the settings panel. If I play a video in Sage I see my system tray shuffle for a quick second, but the icon disappears. I uninstalled the Aopen drivers before installing the official ones. (and before that I had 2.55) Any ideas?

I can access the panel through Radlight, but that seems a bit roundabout when I should be able to get to them the normal way!

This is running on an FX-5200. I had the 61.77 drivers, and also tried the 66.81 betas.

Thanks!

That means you aren't actually using them, they try to load, but fail. Make sure you have them selected in the video settings of detailed setup.

Hmm. The NVidia Video Decoder was selected. I also have an NVidia Video Post Processor (which results in a black screen when playing video).

With the Video Decoder, video plays fine, just the weird behavior with the system tray icon. Perhaps I need to do some more in-depth cleaning of the codecs, and re-install?

Thanks!

try updating to the newest beta
it seems to have fixed the issue where 1.0058 and 4.0029 would crash SageTV when accessing the control panel
