I'm having performance issues playing DVD's on a 2.0 Ghz P4 laptop (Dell SmartStep 200N). The video is choppy and just can't sync up with the audio. My video card is an ATI Radeon Mobility, and I'm using the Gatos drivers. My sound card is an Intel 82801BA/BAM AC97, and I'm using OSS drivers for it. Nothing else is using the sound card (I checked with fuser). The DVD drive is an IDE device, and has DMA enabled. I've tried numerous combinations of options with mplayer (dga, xv, x11, fbdev, and sdl for video out, and oss and sdl for audio out), and nothing seems to help. Not even -framedrop. I'm using mplayer 0.90pre9. Anyone have any suggestions? It seems quite odd that a 2 Ghz laptop should have performance issues with this stuff.. -- Mike Perry Mad Computer Scientist fscked.org evil labs

I had the same experience (different hardware though) but I found that the slowness was due to the fact that MPlayer was unable to use alsa9 as output (I had forgotten to recompile the drivers) so the sound disappeared and that made mplayer play at 50% speed instead of a 100% ... Strange, but fixable. Dunno if it helps you, but it might shed some light on the issue (?) /Henric ----- Original Message ----- From: "Balatoni Denes" <pnis@coder.hu> To: <mplayer-users@mplayerhq.hu> Sent: Sunday, November 10, 2002 1:31 PM Subject: Re: [MPlayer-users] DVDs slow on a 2Ghz P4?

My "magic recipe" :-) for a fast media player is this (the first is the most important, the last is the least important): - enable DMA on the DVD - use Xv for video - use ALSA for audio When all these conditions are met, the CPU usage is the lowest. Your mileage may vary. ;-) On Sun, 2002-11-10 at 13:24, Henric Andersson wrote:

Does it play fine without sound ? FWIW, with OSS sound drivers on dell laptops I have had to add: alias sound i810_audio add options i810_audio clocking=48000 for the kernel module options otherwise the sound sometimes goes wrong... Trying and launching mplayer with -cache may help too. -- Best regards, pl
