1080p freeze ups

[help]

My PC can play 720p using Media Player Classic + CoreAVC but I can't play 1080p properly because of video freezing and audio lag.
Characteristics of my PC:
Intel Pentium 4, 3000 MHz, 512MB RAM, ATI RADEON 9200 SE 128MB.
So... what is the problem? :confused:

[Dark Shikari]

The problem is its simply too slow.

[help]

If I buy more memory it solves the problem?

If I buy more memory it solves the problem?Buying a car a bigger gas tank doesn't make it any faster. More memory won't compensate for your slow CPU.

[help]

So I need more memory, a better CPU, a better Graphic Card? A new computer...?

You need a much faster CPU--CoreAVC might be fast enough on your CPU, or it might not, you're really borderline even with CoreAVC.

buy a cheap ATI/AMD card with UVD core + Cyberlink PowerDVD and your problems are history at least for VC-1 and H.264 (Mpeg-2 will be as fast as with your current card maybe a small percentage faster) (under Windows) tough if you think about buying a card that's more expensive then a XboX360 (200$) think again (it doesn't make sense for your PC) for this purpose then i would advise you get a Xbox360 maybe a used one for even less from a "Purchase and Sell Store" ?
With it you have the same posibility as currently with your PC to upgrade later on to a HD-DVD Player for additional aprox 140$ bucks @ the moment (this way you have a relatively cheap Microsoft 3in1 Device in your House) ;)
Another Solution would be a DSP Player with Hard Drive (or without) but those are still to expensive compared to a Xbox360 and it's Power and Versality (tough their Energy Usage is in general lower then all the other solutions).
As i said the cheapest solution for you (if Energy Usage isn't that important) would to buy a UVD core Card and later you can even build your PC into a Blu-Ray and/or HD-DVD player (it's your choice) tough for that you need to stay HDCP compatible with your Monitor (DVI/HDMI with HDCP same with the Dsp Player and Xbox360).

Cheapest Solution for help:
http://www.gpureview.com/show_cards.php?card1=526&card2=391 (This is your possible Hardware Solution but you need additional Software (see the following Solutions bellow) to use it at least for AVC and Mpeg-2, VC-1 Hardware Decoder comes with Windows Media Player 11 for free)
http://www.cyberlink.com/multi/products/popcompare_1_ENU.html (without HD-DVD and Blu-Ray support, you can download a Trial of it first to test it) (even possible to save this money as some GFX vendors bundle PowerDVD 7 with their Cards in Oem versions that comes with all filter you need same as the trial, but it isn't so easy to find out wich Vendors and in wich package there can be different like Bulk/Lite-Retail/Retail)
http://www.cyberlink.com/multi/products/popcompare_112_ENU.html (For HD-DVD and Blu-Ray support)
http://corel.ec-shopping.net/shop/COREL010/default.php/cPath/3_69 (also a possibility but it's not out yet in the US i think)
http://www.nero.com/enu/nero8-introduction.html (if you compare it for your purpose to the other solutions it makes no sense to expensive @ 80$ + Blu-Ray/HD-DVD plugin add Extra cost of $24.99)
http://www.nero.com/eng/technologies-nerodigital-player.php (here you can Trial Neros Video Solution without all the other Stuff, not sure if you can buy it seperately anymore i don't think so)
http://www.elecard.com/products/products-pc/consumer/avc-plugin/ (also a Solution but im not sure if it works with the new UVD core last tests i did was on VP1 and it wasn't that successfull but you could try it after buying the 2400 there are Trial Versions for Download)

Damn...

What you could try is: disable deinterlace, if you've already updated your coreavc to 1.6.0.0 this option is unavailable, so you would have to wait for the new 1.6.5.0 release.

Allthough this setting will not give you smooth playback on x264 @ 1080p. It'll atleast lower your cpu load. Maybe increase performance on x264 @ 720p

I don´t understand that! On my Dell (P4 3000MHz, 1GB RAM 800MHz, ATI Radeon 9250) the 1080p Coral Reef Adventure Video from
http://www.microsoft.com/windows/windowsmedia/musicandvideo/hdvideo/contentshowcase.aspx
plays fine in VLC, the CPU is not even on 100%.

He's probably having trouble playing H264, and not VC1. It also may depend on the bitrate and complexity options the stream uses. I can play most 1080p H264 streams up to around 15-17mbit with coreavc and deblocking disabled. H264 streams that need deinterlacing lag and higher bitrate stuff usually does too (at least to some extent). Specs are the same as help's (maybe graphic card differs, I can't check right now). So yeah, maybe disabling deblocking and diabling deinterlacing in CoreAVC might help. If it still lags, upgrading seems the only viable solution.
