Not sure how often I've said it... When playing (ripped) 1080p videos especially those in MKV container format, processor speed is much more important as it does not fully rely on GPU HD video decode acceleration... as the above results (mADmAN) have already shown. Heck, I can also play 1080p videos on normal GPUs without HD video acceleration.. just need the right processor. wink.gif

I'm pretty sure you need to do more research. Most ripped 1080p videos work with DXVA in MKV format. However, you will need to use MPC-HC. An easy way to configure it would be to simply use the latest K-Lite Codec pack. Google "x264 DXVA"(without the "") and the first result will give you the link on how to make 1080p videos work on GPU acceleration. Btw, for really tight-budgeted HTPC rigs, it's where GPU decoding shines. Still, there's no point to use GPU acceleration if you have at least an Intel E5200 though.
MPC-HC will only work if the video stream complies with DVXA standards, otherwise it will revert back to (intensive) software decoding. And I have tried on many systems and I can tell you that with 1080p MKV you'll need a fast processor as many of the players I've tried does not use GPU acceleration at all (should be due to the way MKV demultiplexor handles the codec part). wink.gif

Quote from CCCP moderator on MKV playback problems..

lots of people have this problem. The solution is almost always: a) use a more efficient decoder (read: coreavc) & b) get a faster CPU.

You've been repeating the same thing like a broken record. We know that already. Anyway, does DXVA work on your end with the guide I gave you?
I tried those many (many) moons ago, same thing.. does not work with GPU acceleration. Cards tested.. 8600GT, 8800GT, HD2600XT, etc.. etc.. tongue.gif

Too bad for you then, it works for others, though I hope your settings were the same with mine.
MKV playback does not work with GPU acceleration.. period! rolleyes.gif I need at least a E6600 (with slight overclock) and X2 5400+ to get it running properly and (almost) very smoothly. Whatever settings you've mentioned, it comes back to the processor again. Video lag is a very good indicator (sound comes first, not in sync with picture).. And re-encoding the video to MP4, WMV and AVI just to use GPU accelerated players is not something I would like to waste a lot of time with. wink.gif

I checked out both the motherboards u suggested accs_centre, but both of them are over RM 400... which, sadly, exceeds my budget... generally all the G45 chipset based mobo's are really expensive, is there any other alternative?
Cheaper alternative: GigaByte GA-73PVM-S2H brows.gif Other alternative, get a cheap G31 chipset motherboard and install a cheap HDMI ready card. tongue.gif Anyway why worry about the GPU acceleration part? The processor is already fast enough to do it in software. nod.gif

QUOTE(howjimmy @ Feb 12 2009, 03:26 AM)
how about the PSU? is there any type that i should look at? because i'll be leaving my computer on 24/7 and im planning on getting maybe two 1TB HDDs for BTing biggrin.gif
Get a good branded one, definitely not cap ayam ones. I'm currently using Delta and AcBel for 24/7... previously was Enlight (HPC OEM). wink.gif

QUOTE(howjimmy @ Feb 12 2009, 03:26 AM)
On a side topic, im using a MSI 945GM3 motherboard now, do you think that it is capable of running HD and Bluray movies? or would you guys here recommend that i get a new mobo?
It can run those provided you change the processor... suggest at least a Core 2 Duo E6600 and higher (the faster the better). Since it doesn't have hardware decode acceleration, will rely mostly on processor speed for decoding thus the faster the processor the better. wink.gif The problem is finding a fast 65nm processor nowadays, usually you would have to look around in the garage sales... hmm.gif

sounds like good advice, was thinking for going for the g31 mobo and adding a graphics card, on top of grabbing the E5300... any suggestions on what gpu i should get? i was looking through and i saw the geforce 8600gt, i was thinking of that one because it has the purevideo technology
Make sure the graphics card has HDMI, or otherwise get a DVI to HDMI adapter. Even the lowly 8400GS also has PureVideo. wink.gif

By the way, the GigaByte GA-73PVM-S2H is around RM295 to RM340 and comes with HDMI already but its not an easy board to find. hmm.gif

QUOTE(howjimmy @ Feb 12 2009, 05:37 AM)
How many watts do you think i should go for? 550w?
Looking at the specifications, a true power 300W to 400W would be suffcient, since most of the hardware are low power. You'll only need a 550W for a gaming machine with more powerful graphics cards such as the GTX260+, GTX280 and HD4870. icon_rolleyes.gif

400W true power (not too sure)
QUOTE(howjimmy @ Feb 12 2009, 06:06 AM)
what do u think?
Below are considered 400W+ PSUs under the "affordable" list...

- Silverstone Strider ST40F 400W
- Gigabyte SuperB 460W (real power 400W)
- CoolerMaster Extreme Power Plus 460W (real power 420W)
- AcBel E2 Power 470W (real power 420W)

This is the correct list: MSI 945GM3-F CPU Support List. As I've mentioned before, this board supports 65nm dual cores mostly. Re-quote from here.. wink.gif

Whats your total budget, by the way? hmm.gif

so it does support it?
Nopes, your current MSI 945GM3 motherboard does not support 45nm processors such as the E5300 nor E7400. wink.gif

QUOTE(howjimmy @ Feb 12 2009, 06:38 AM)
thank god or rather lex, i was wondering where i was going to pull that extra cash from! tongue.gif
so im going to upgrade the processor to the e4700/e5300 and get a hdd and psu, what do u guys think?
The 65nm E4700 is supported on your current motherboard. smile.gif

But I don't think you can find the E4700 in retail anymore nowadays, its EOL'ed. hmm.gif

QUOTE(howjimmy @ Feb 12 2009, 06:38 AM)
i've got 2 PATA 160gb hdds and 1 250gb sata hdd, because im using a mid tower now, if i add on another hdd would it affect the electrical flow of the computer if i were to not buy a psu?
So many HDDs? sweat.gif I would suggest a true power PSU of 400W and preferably higher. nod.gif

Looks nice, but the specs kinda sucks...Intel GMA X3100...

http://us.shuttle.com/Dvo.aspx

Starting from USD 999!!!! sweat.gif

Can built incredible DIY HTPC for that kinda money.
The heavy price is most probably due to that touch screen LCD in the front... hmm.gif Nice "touch" by the way. laugh.gif

Guys, i've a strange problem. I have K-lite codec and MPC-HC installed. Most of the time i set to passthrough DTS/AC3 to my HTIB via optical out.

However, sometimes i need to disable the passthrough when i want the sound from my analog speaker. The weird thing is after sometime, the passthrough option simply went missing from the MPC-HC 'output' options.

When i re-install the K-lite+ mpc hc again, it re-appears. Anyone knows why? rclxub.gif
Check your sound hardware settings... Also you might want to try CCCP... wink.gif
