Re: [mythtv-users] Pre-buffering pauses on Toshiba 4300 laptop
From: "Chris Rouch" <[EMAIL PROTECTED]> My compaq M700 (P3-700MHZ, 256MB) shows the same symptoms. Additionally if I use mplayer with '-zoom -fullscreen' sound and vision quickly go out of sync, and it complains that my system is too slow. My guess is that laptops as slow as mine (and yours) really are too slow for this kind of task. I'd agree with you there if it weren't for the fact that my Dell laptop (P3-600, 256M, S3 Savage/IX) which is very similar to the Toshiba seems to be able to play these clips perfectly fine. I did some playing around, dropped the X colour depth to 15 bit, and now have ~15% idle time on my cpu when playing myth recordings. Unfortunately I'm still getting pre-buffering pauses. Looking at the "-v playback" logs from mythfrontend I see that the audio begins to lag by a few frames then the pre-buffering pause will hit. I wonder if there may be a problem with audio (yamaha chip) or the machine is RAM starved (192MB). Time to dig through the ALSA archives and hunt for some more RAM for the laptop (although something tells me 192MB was the maximum RAM this machine could take). Still looking for ideas, Shawn Flynn ___ mythtv-users mailing list mythtv-users@mythtv.org http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users

[mythtv-users] Pre-buffering pauses on Toshiba 4300 laptop
I am currently trying to setup an old laptop as a frontend only box for my MythTV system (details below). Everything is installed and running ok, except that I get pre-buffering pauses when I try to playback any of my recordings. Looking at 'top' it appears that the cpu is being pegged at 100% during video playback (65% mythfrontend, 35% X). This laptop _should_ be fast enough to playback the videos as I can play them back on another frontend with a slower processor. Can anyone offer some suggestions as to where to look to improve performance for this machine? Toshiba Sattelite 4300 Pro, P3-600, 192MB RAM, S3 Savage/IX Fedora 3 and Mythtv 0.17 installed using Jarod's most excellent guide. Using internal LCD panel @ 1024x768 as display (Laptop has TV-Out but I won't be using it) xvinfo tells me that XV is running for the Savage/IX video Video clips being played are [EMAIL PROTECTED] mpg2 captured with a PVR250. Video clips are ok as I can play them with my celeron 533/ATi Rage frontend machine without pauses. Any suggestions for troubleshooting this?
