So i've now tried playing Cloverfield and I Am Legend 1080p BluRay rips, but they lag from time to time.

LOTR: The Return of the King works fine though.

I've tried VLC, Media Player Classic HomeCinema Ed. and WMP. Seems to work best in WMP, by some weird reason.

I have ffdshow and Haali Media Splitter (codecs are really not something i know much about).

This is on a C2D E6750, 4 gigs of PC6700 DDR2 ram and a 8800GT..

No reason for that to happen. But since you have an 8800GT, you should use PowerDVD's h264 decoder, because there's hardware acceleration.

increase the read buffer in haali splitter
that should help a bit
disable unnecessary postprocessing from ffdshow (essentially all but h264 deblock)
also, make sure antialiasing isn't forced on and try switching the video renderer
if it still lags, use a hardware decoder or coreavc

Hm, im thinking it might have something to do with my disk access speed? When transferring files between my disks, i have a maximum of 50 mb/s. And can't be right.

Or is the transfer-speed slow just when tranferring, not opening a videofile on another harddrive?

Yeah, i'm running Vista.

... and then choose to use it for h264 in MPC. The problem with powerdvd is that it doesn't support .mkv or the embedded subs.

Don't use PowerDVD's player, it's complete bollocks. Use their decoder in WMP, MPC, etc.

How much power does 1080p needs? Is a C2D 2x2Ghz enough?

I remember the new Batman Trailer @720p stucking with VLC and Quicktime Sad

Why not? It's fine. It's slower then the rest, but with 720p it's more than enough. I can watch 1080p movies on it fine as well.

I had lots of lags with 1080p using my cpu to decode. I just prefer MPC over VLC because there is no video controls in full screen with VLC, which makes it fucking useless for HTPC.

Nouse, try this:
http://en.wikipedia.org/wiki/The_KMPlayer

It's great for HTPC, and allows you to set up external codecs much easier. Plus it has a much nicer interface.

There is no point, very few full HD 32". In fact the onces that excists are even more expensive than most 37" full HDs. Its very rare I download 720p too, only really good movies ^^

I might sound like a noob , but i got powerdvd 8 installed , when checking external filters in MPC i see a bunch of cyberlink codecs but none have 264 in them.

I basicly want to get UVD support ( for kicks ) since i got an ATI card and read alot of good things about it , google search told me its only supported under vista 32 bit ... ? and that it has issues with MKV files , so basicly its useless if you dont play bluray or HDDVD ?

At the moment on a AMD 6000+ x2 a 1080p video will take 33% cpu usage at max on one core , zero lag etc. Using the standard ffsshow decoder that comes with it.

With coreavc its about 27% percent, but i miss out on the ffdshow video settings ( i really need the gamma etc settings )

So im fine for now, but this year i would like to build a HTPC which has to be as cheap and low power usage as possible , hardware acceleration through GPU would be a huge help.

my 'mediacenter' based on P4 @3.4ghz + 6800Gt runs 1080p perfectly and stutters only when there's rain or a lot of leaves. So lol @ C2D.

You can enable ffdshow to read uncompressed video and you'll have all the ffdshow perks while using the CoreAVC (or any other) decoder.

as far as you know only the powerdvd codecs have GPU support for h264 ? wouldnt mind trying those out on h264 encoded mkv rips what i would primarely use. If it only works for bluray and HDVD than it would be quite a let down and useless to me.

Yes, currently only Cyberlink decoder supports HW acceleration. CoreAVC are however scamming people into thinking they will be adding HW acceleration soon. Wink

should be noted that coreavc does result in a slightly blurred image when compared to,say, ffdshow's decompression (which uses the reference decoder)

also, if you don't have a huge screen or a majestic projector, 1080 is overkill.. 720 has half the cpu impact and you wouldn't see any difference in most films
but having better quality never hurt anyone Smile

Yeah, I THINK the image didn't look as sharp as with ffdshow, but im not sure.

But it's silly that it has to lag really - i should be able to play 1080p without any hassle whatsoever!
I mean my PC CAN handle it without any problem, there's obviously something else that's wrong..

The only thing that fixed the lag for me was Core AVC Pro + MPC. Works perfect everytime now.

Are you using the combined community codec pack? If so than

start>programs>cccp>video decoder

look for H.264/AVC and click the drop ddown list and choose disable

he did say he has ffdshow
which is the same thing

are you sure you disabled all the unnecessary filters (essentially all) in ffdshow video decoder?
