[mythtv-users] TV and mythmusic jerky

Hi,

I've read some reports about jerky video, but found few workable answers, but 
I'm hoping my extra symptoms may prompt suggestions.

In addition to jerky live and recorded TV, I also get jerky music from 
mythmusic.  By contrast, KDE TV and Amarok have no difficulties with TV and 
music respectively.

My hardware is
    *  Barebones: EZ-Buddie2
    * Graphics: XFX FX5200 Personal Cinema
    * TV card: Leadtek WinFast 2000XP Deluxe
    * Processor: Celeron 2.26Ghz
    * Memory: 256Mb
    * Hard drive: Maxtor 80Gb
    * DVD: NEC DVD R/W

I'm using a Mandrake 10.2 multimedia kernel and also have added rtc as a 
preloaded module, so I think i have everything that I could possibly have to 
improve performance, but the results remain poor.

Simon
