My major area of concern is in MPC and setting up filters etc for quality playback. I've already troubleshot to the point that my system is not fast enough for madvr so instead use lav video decoder with evr-cp renderer.

I can playback files, but every once in a while the screen tears or is a touch jittery. In addition, I am getting a lot of 'snow' in my playback of mkv files.

I can only get my monitor to set at 60hz because of an nvidia resize issue; dropping frames and jitters can be caused by this? I have tried multiple ideas from doom9, here, and other forums but still feel as though the playback picture quality is inferior. I am having a lot of snow (artifacts?) in my playback of mkv files and a lot of blotchiness in the background video images in mp4 files.

I was using the cccp setup but one night I had a trouble file and messed up my settings pretty badly so decided to cut back to standard mpc-hc and installed the lavf video decoder. After that I installed and tried madvr as the renderer but my system couldn't handle it.

In addition, my nvidia geforce 9200 scaling option has no effect on my computer whatsoever (when I spoke with them they had me report it as a bug). Because of the scaling option not working properly I have to resize my desktop with Nvidia because the edges of the desktop are off the display screen. Due to that, my screen refresh rate can only be set to 60hz. I'm pretty sure this makes a difference in the jitters and tearing of my (fullscreen) video playback.

I know something is not right, but I can't trouble shoot it properly. I don't know enough about what I'm doing, but am eager to learn!

GeForce 9200? Hmm, you'd better upgrade it to something decent such as GeForce GT 630 (= 440), then discuss again. What are your CPU, RAM and motherboard?

I am on a very tight budget. I would LOVE to upgrade any one component of my system but as a laid off father of two toddlers, money is tight. I do not have an elitist machine. It's garbage and was manufactured 5 years ago. I've seen it look nice during playback before, but it was someone else's settings. I'm not sure how to check motherboard; rest as follows:
2.10 GHz amd athlon dual core processor 4050e
4.00 GB ram
64 bit Vista (yuk, I know)

Thanks, Bob.

After a little bit of poking around: my psu is only a 220 watt.so even if I could afford to upgrade my graphics card (which would be way down on the list because my subwoofer for my home entertainment system short circuited out over the last couple days argh), I'd have to be very careful which one i got and and wouldn't be able to upgrade too far or upgrade the power supply as well.

I hope my system isn't so obsolete that we can't find a way to maximize its success through settings/filters, etc.. Thanks again.

You can get a HTPC appropriate video card for $20-$50 that can do HD audio, 1080p, etc that will use less than 50 watts.

That's definitely good to know and will come in handy if I can find some work. But, like I said before, I am out of work right now, have two toddlers, 2 dogs, 6 cats and a parrot, all of whom I have to keep fed and clothed; even 20 to 50 dollars is out of my price range for now. Also, my poor subwoofer shorted out, so that kind of takes precedent over a new video card or psu (which I also found relatively cheap.)

Are there any checks or logs I can post so that someone could possibly analyze my current situation?

Will that graphics card work with my cpu and ram? What specs should I know when I go into the electronics store? (I heard through the grapevine I'm getting a gift card for my birthday this weekend.) I will absolutely upgrade. I have (an older model) plasma tv and know I'm not using it to its full potential. I'm going to check the price on the GT630 now but my price range is probably less than $50. Thanks for any additional info.

I do have a further question: is it my ram, my weak graphics card, or some other issue that makes the madvr codec make video playback slow or jumpy?

Your graphics card is the weakest part. Athlon X2 4050e was released in 2008. So your system is not terribly outdated and any PCI Express graphics should work.

GT 430 or GT 630 with effective memory clock >= 1600MHz is recommended. For examle, Galaxy, ASUS, GIGABYTE.

Galaxy - 210 Series NVIDIA GeForce 210 1GB DDR2 PCI Express Graphics Card is more in my pricerange. is this an upgrade from the 9200? I'm at a loss. I don't want to take a needless step in the wrong direction.
Thanks. Bob.

You won't see much improvement by going with 210.

Asus - ENGT430/DI/1GD3(LP) Graphic Card

GeForce 430 - 700 MHz Core - 1600 MHz Memory Clock - Fan Cooler - 1 GB DDR3 SDRAM - PCI Express 2.0Low-profile

GeForce GT 630 - 810 MHz Core - 1300 MHz Memory Clock - Fan Cooler - DirectX 11.0 - 2 GB DDR3 SDRAM - PCI Express 2.0Low-profile
$73.81

This is about where I'm at. I know it won't be much of a difference, but if any, which is going to give me a better picture quality?
Thanks again. Bob

I didn't realize until I was ready to submit this that the examples you left were links. I will look at them now.
Those look to be similar/same cards. Too bad I'm not getting a newegg gift card; prices are much better than Best Buy.
