i'm not sure i 'm very clear,

with 2 differents dvb card (hvr1110 & hauppauge hybrid pro stick) on my 
pc, i have the same problem on a channel called M6 : little squares on 
screen and disturb sound and then no sound.

Then i test the hybrid pro stick on a laptop (here i can't test my 
hvr1110 : pci card) with the same operating system : on the same channel 
and at the same site (my house) all is good :  good reception and 
beautiful picture on channel called M6.

So i think there is a problem with my hardware configuration, here is why :

when my main memory is configured in bios at 100Mhz, on ALL channels the 
results are the same : little squares on screen.

i can configure it to 133Mhz and the problem is only located for M6.

So something is lost with  transfers between main memory and pci bus.

but i can't upgrade to 166Mhz (bios limitation). so ...


However, i will try what you suggested and provide feedback

Thanks for your answer.

Tom.



PS : sorry for my very bad english .
