The problems I was seeing was with just catting /dev/video0 to a file, and it would hang immediately with several DMA errors (and a zero length file). I wasn't even running myth yet. Since that time I have run it in PIO mode under myth and it seems to be ok (albeit with 30% CPU). The interesting thing is that last night I updated to the 0.10.3 package from gentoo (I had 0.10.3 from source on the system previously) and I found I had "optimize for size" (which I read caused someone issues with ivtv) set in the kernel config, which is something I usually don't do. So, I recompiled the kernel without "optimize for size" and then updated to the 0.10.3 package, and viola, it now seems to work fine - no DMA issues..... So I am happy, but also surprised. Thanks for the tip, Rett Walters _______________________________________________ ivtv-devel mailing list [email protected] http://ivtvdriver.org/mailman/listinfo/ivtv-devel
