I'm mostly done putting together the myth box, but I ran into a problem I did not expect, not with the hardware I put together: video playback is stuttering quite badly. It does not happen all the time, but mostly in these two cases: 1) After I switch channels in live tv, there is a pause (expected), then it starts playing, pauses, resumes, does it several times, this lasts for 10-20 seconds, then it starts playing ok. 2) If I pause live tv and then play it after a while, video stutters and pauses, and it gets worse the longer I wait. If I paused for an hour, it'll be impossible to watch, it'll halt every few seconds for half a second, and unlike the case above, there is no end to this.
I'm running FC3, 2.6.11 kernel, latest myth and ivtv from atrpms (myth 0.18.1-111, ivtv-0.3.5l-92). The box is built around Soyo Dragon2 motherboard, Athlon 3200+ CPU, 2GB of dual-channel RAM. When video stutters, I often see disk light come on, especially in the second case, so here is more about disks. There are 4 Seagate 300GB ATA disks in the box, with two software RAIDs: /dev/md0 mounted as /, raid1 built from hdb1, hdc1, 20GB, ext3 /dev/md1 mounted as /raid and used for all mythtv files, raid5 built from hdb3, hdc3, hde3, hdf3 (currently runs in degraded mode until I add 5th disk), about 1TB, JFS. hdX2 are swap partitions, 1G on each disk, striped. Seems like I need to tune the system for beter I/O performance. Any tips?
