[ivtv-devel] ivtv 0.4.0 pvr 500 stealing buffers and corrupted recordings

Geoffrey Kruse Sat, 15 Oct 2005 22:45:17 -0700

I am also seeing the same problem described in the two links below. However, my disks are not full and this problem is totally non- existent if I switch back to 0.3.7k. When watching recordings, there are green blue and grey blocks (corruption) all over the image. Is there any additional info I can provide to help fix this? I need the sound fixes in 0.4.0, but the corruption is making it impossible to use this version. This is all on a celeron 450 w/ 192 mb of ram. ( I know this is a slow system but it worked with 0.3.7k)


The error is as follows:
...
