For 9.1 (should be OK on 9.0 too) kernel-multimedia-2.4.21.0.16mdk-1-1mdk kernel-multimedia-source-2.4.21-0.16mdk (on cooker /contrib (RPMS2) mirrors) "This kernel includes patches useful for multmedia purposes like: preemption, low-latency and the ability for processes to transfer their capabilities. The preemtion patches allow a task to be preempted anywhere within the kernel, using spinlocks as markers for non-preemptibility regions. The resulting system response is greatly increased, with measured average latencies under 1ms. Andrew Morton's low-latency patches fix the remaining points in the kernel that cause latency. The setpcap patch allows suid root processess to transfer capabilities to non-root processess, and so making it possible for user processes to run with realtime priority." No discernable improvement seen here, but I use it anyhow ;) -- Tom Brinkman Corpus Christi, Texas
