8 megs on built in video

[letulechuga]

i have this p3 with 256 mb ram that, when paying back video files and dvd's.......gives me some lag....

my question is whether it's the 8 megs of video that creat the lag.

thanks,

At is the best.

Of course not. Much more likely, it's lack of CPU power combined with lack of hardware DVD acceleration in the graphics card.

DVD has been successfully replayed on 233 MHz Pentium-MMX and 4 MByte graphics cards (SiS 6326DVD, the very first one to offer DVD acceleration).

Without DVD acceleration hardware, you'll need around 500 MHz of CPU power.

 

[letulechuga]

the cpu is 800 mhz

And what is the hardware that you are talking about?

 

[Peter]

Graphics cards - today they all have extra hardware assisting the math in DVD decoding; older ones rarely did. What's the card in that system?

 

[letulechuga]

ohhh..

it's some onboard stuff, I think by VIA, that's probably why.

It only has pci slots, do you think like a geforce 4 pci or a radeon 7000 would do the trick?

 

[ForumMaster]

it might. for example, all new cards (such as the nvidia geforce 6 series that include purevideo) have dvd and movie acceleration. i think a geforce 4 might be better.

I recall from the old timey days that graphics chips with the requir'd iDCT and MC hardware acceleration only had that functionality via AGP. The difference may have become irrelevent with advent of DXVA but in any case confirm the PCI card's actual specs before buying (or better yet user experiences) and don't rely upon the chip specs.

Of course a software decoder which utilizes all the chip's abilities will be requir'd which prolly means a commercial one rather than a freebee, although the former may be included with a card or a DVD drive &c.

Really though, a P800 should have no trouble with full software decoding so it may just be a matter of trying a better decoder or else the lag is a symtom of sumfing else such as the storage controller config in PIO rather than DMA mode.

What VIA graphics engine exactly? Ye olde Trident in PLE133 chipset, or some more recent Savage engine? The former is hopeless, while all the later ones might do MUCH better with fresh drivers.

Trying playing the DVD in a window and disable any special video/audio enhancements if possible.

 

[letulechuga]

i'll see what the chipset is exactly

I tried playing a DVD and it worked with almost no lag, but a ripped movie was lagging pretty badly and it's resolution was 592x4.. something.

And all the problems start in fullscreen with the ripped one. And also when using media player (9series) it lags in either mode and when using some other player it's all good.

 

[Peter]

Your DVD vs. ripped result would suggest that your graphics hardware does have DVD decode assisting hardware, but (quite obviously given its age) no DiVX or MPEG4 decoders - and that weak CPU can't do those either.

Do tell us what chipset you have there for the final verdict

My first high-end laptop had MPEG 2 acceleration. Did not have 3D acceleration though.
I believe it was a Celeron 266.
Movies were great. Games sucked. Except for old DOS and Win95 software 3D games like Wing Commander 4 and Quake.
Soon as I played Quake 2 I knew I needed something better.

The next laptop had an 8 Meg Rage LT.
POON!

 

[letulechuga]

the integrated chipset turned out to be an intel one with 32megs of memory it is a 82810

i'll download some drivers for it to see if that'll do it.

 

[letulechuga]

the drivers on intel's site turned out to be older than the one's i had, so that's no help
