| 764578 | 2009-04-13 05:13:00 | I have an asus 901 up graded to 2g RAM and a 64G second sdd. Recently I have noticed it seems a little sluggish when viewing film ( h264). Using Process explorer it seems when I watch video with vlc (0.99) or play .org sound files with medi monkey 3.0. The deferred procedure call can run upto 30%. This doesn't happen as far as I can tell when surfing or word processing etc. So I am thinking off trying upgrading the drivers for sound and video. Is there anything else it could be (other than virus/malware) ?? |

| 764579 | 2009-04-13 05:21:00 | The Deferred Procedure Call service allows higher priority tasks to defer lower, required tasks for excecution later. Basically means more important stuff such as watching your movies will be handled at a higher priority than other stuff. My opinion here is that the CPU and Interated GFX in the eee 901 simply cannot handle this much-and the system is already giving its full power to VLC. This could also be due to a slow SD card, but I doubt it Blam |

| 764580 | 2009-04-13 08:47:00 | As the DPC's seem to appear during video and audio, I tried chasing audio options. Turned off dolby with the realtec HD audio and the DPC dropped from 30% to 5% with resolution of the stutters. I agree that lacking power could have been an issue but wont the cpu+DPC add up close to 100% usage? With dolby on the most total usage I got was 50% ie 30% DPC and 23% vlc?? Thanks for your reply A. |

| 764581 | 2009-04-13 22:33:00 | If you try using different audio decoding options, its also worth you looking into something like CoreAVC & Media Player Classic HomeCinema (MPC-HC). Ive used CoreAVC myself on my EeePCs and it was brilliant! :) | Chilling_Silence (9) | ||
| 764582 | 2009-04-20 00:21:00 | Was using handbrake using the Basic normal presets. Got blade runner down to 1.4Gb which was small enough for a first attempt. Uses x264 I think. I have heard that x264 makes smaller file but more processing to play? What format/codec are you using with your eee? Aim is to be able to watch on planes and not to output to anything other than the eee. A. |

| 764583 | 2009-04-20 02:24:00 | I only use VLC as a player of last resort; as you have found, it has horrible performance. I agree with Chilling: MPC will generally give a better performance. Using it with CoreAVC will improve performance still. afe66: Yes, h.264 is pretty much the best codec in terms of quality and filesize, but it requires a lot of processing power. |

| 764584 | 2009-04-20 02:30:00 | utopian201, it doesn't actually have *horrible* performance, far from it in fact (when comparing it to other players such as XBMC, Nero ShowTime etc). CoreAVC is just *better* on [b]underpowered[/u] systems. afe66, as utopian201 mentioned its called "h.264". x264 is the name of the encoder used to give h.264 video (There's multiple different ones that each offer varying quality of h.264 video). Try doing a 2-pass video encode, much better quality! You should be able to have it right down to around 7-800MB for a movie :) |

(I think handbrake does this my default) The original source is processed twice before encoding. Re-compressing the already compressed file will result in a horrible, blocky looking movie. |
