MKV playback

[unknownguy]

Hmm guys i am not sure why this is happening but when i play an mkv normal quality (not even 720p) my p4 computer with 7600gs cant handle it.. i can hear my hdd spinning loudly and non stop.

but when i play this mkv on another computer p4 and on board intel graphics there is no problem. computer ram wise the first computer still wins hands down. what seems to be the problem here ?

What Pentium 4 do you own? You need at least a 3Ghz P4 or 1.8GHz core duo to play HD files.

An Intel 965 chipset with GMA3100 onboard grapics has a 667MHz core clock speed and 384MB memory.

The 7600gs only has 400MHz and 256MB of memory. That might not be enough for HD.

I gave my brother an Intel board with the 965 chipset with onboard graphics and a 3.2GHz Pentium D with with 2GB DDR2 800 memory and it plays 720p fine but has problems with some 1080p. That's why I built the P35 with Q6600, 2GB DDR2 1066 memory and ATI HD2600XT. It plays everything I've thrown at it.

MKV is just a container that supports various types of video compression
(MPEG, WMV, VC-1, H264, VP7, XVID, etc). Only H264 and VC-1 are insanely
hungry for data-processing power/speed. I have a 1.5GHz Pentium IV
with an old GeForce2 MX card, and it can playback AVI-compatible H264-video
@ 1024x576 @ 25fps plus stereo audio without sync issues.
720p AVC is already beyond its capabilities.

If the hDD is spinning a lot then you may not have enough memory in the system to play the video without resorting to virtual memory. If you have only a single HDD, and are playing the MKV back from the same drive as you are paging to and from, the system will have an I/O bottleneck that will make video playback virtually impossible.

hmm well the computer i am having problems running is p4 3ghz with 3gb ram gf 7600gs. the other computer with p4 2.2ghz and 1gb ram and gf4 runs the video at 100%.

is it that my rams are failing on me ? or is it my hdd ?

the video played on both computers are the same and not in HD. its normal quality.
