Sorry. AC3 is pretty good (presumably because the sound card is doing nothing to it) -- normal audio through the S/PDIF port seems to really chew CPU. > i'm not sure which version of the patch this is.

It's using the patch that comes with the ivtv driver in the latest 0.3 tarball. mplayer comes back and says that the CPU is too slow, and to try the autosync or to use OSS instead of ALSA (among -framedrop and so on). I'm genuinely curious, why is "normal" audio so hard on the CPU? > > ivtv-fb doesn't seem to initialize correctly on my > > system -- the framebuffer > > is "skewed" and if I use -vo ivtvfb I can see that > > it's playing to the > > framebuffer, but it's not viewable due to the skew. > > yeah i forget why that happens.

I'll play around a bit more... right now I'm trying to figure out why it takes 10 years to boot from the network on 2.6... 2.4 was working perfectly, and I'm imagining it has something to do with NFS locking even though that's all been turned off. I haven't tried the X11 driver yet. Don't have X installed. :-) -A. ------------------------------------------------------- This SF.Net email is sponsored by: IntelliVIEW -- Interactive Reporting Tool for open source databases.
