Hello,

I'm currently testing a new AcessGrid 3.1 installation with 2 computers;
- The first one is a Linux Fedora Core 9 (kernel: 2.6.25.3-18.fc9.i686) 
with 4 video capturers connected to 4 cameras. This computer is working 
as H264 video producer with a Service Manager launched.
The 4 video capturers are Pinnacle PCTV Rave (chipset: Conexant FUSION 
878A).
- The last computer is under Windows XP SP3 working as a H264 video 
consumer.

I start the AGServiceManager on the linux computer and then on the 
windows computer i launch my venue client and i configure there the 
consumer and producer video services. When i connect to my venue 
everything works fine; vic gets launched i can see all the videos 
perfectly and smooth but after a few time, (about 20-30min) one of the 
cameras freezes completly (it's random the camera that freezes) and i 
start getting the same error all the time in the console where i 
launched the ServiceManager:

ioctl VIDIOC_DQBUF: Input/output error

Also if i check the dmesg output i get errors there, for all the other 
devices (bttv1, bttv2 and bttv3):

bttv0: SCERR @ 369d9000,bits: HSYNC OFLOW FBUS SCERR*
bttv0: timeout: drop=41 irq=114623/114624, risc=369d9000, bits: HSYNC 
OFLOW FBUS:

I have checked if the video capturer cards where being loaded with the 
right module and driver and seems they are. 

At this point i don't what else i should check or do, so if anyone got a 
clue about what's wrong any kind of help would be appreciated.

Greetings,
