Hi Paul et al, I'm still stuck and would be grateful for any suggestiongs.
First, I picked up a new video card and processor. Video Card: Nvidia FX5200 Processor: P4 3.06Mhz 533FSB Regarding your checklist, here's what I've done so far. > a) Right drivers for card with your kernel Presently, I've got nvidia drivers version 7174. I tried the 7664 drivers first, but XvMC didn't seem to work, so I went back to my 7174 drivers after reading more posts on the list that said 7664 didn't have a great XvMC track record. However, I still couldn't get any XvMC stuff to work on 7174 under Myth (thought it does work with mplayer). > b) Proper AGP bus speed and AGP interface driver in use I'm using agpart and I in /proc/drivers/nvidia/agp/status I see Status : Enabled Driver : AGPART AGP Rate : 4x Fast Writes : Enabled SBA : Disabled If I enable SBA, I get no video and can't get back to console when I start X. > c) Proper user of openGL sync for retrace I recompiled with --enable-opengl-vsync, but I've still got Video Timing method: RTC Where do I change that? > d) Proper settings for deinterlace and, if used, xvmc I'm not even attempting deinterlaced playback yet. As I mentioned, if I enable XvMC in myth, it segfaults when I try to play back a capture. > e) Proper sound settings and handling of 5.1 sound and multiple streams I'm using ALSA:default and I'm getting sound. I don't know what else to check here. > f) Real time scheduling of playback thread When I run it sudo'd I get "Using Realtime Priority" but that has no effect on my playback issues. > g) Making sure disk or network speed is adequate I'm working off a local disk. hdparm tells me that I've got 51 MB/sec on buffered disk reads. > h) Nothing else sucking up CPU on the machine I'm not running anything else that is CPU intensive. I'm now scoring like 3600 on glxgears. Playback of my 1080i test stream is still impossible and I'm seeing lots of "prebuffering pause" in the related terminal. Is there a "Turn off annoying pauses" checkbox that I'm missing? Thanks!
