There is a problem they are working on for the firewire driver. It is triggered by high deferred procedure call latency (DPC). You can open the Flex firewire driver and enable the DPC monitoring function. I bet that, when you start to get distortion you are getting a high DPC spike. Since it seems to be triggered by video activity there is a chance that your graphics controllers and the firewire interface are sharing an interrupt. You should probably go back through the archives of this list looking for discussion of DPCs. There have been a lot. If you solve the high DPC problem in your computer, the distortion problem should go away. > Setup here is AMD dual core Phenom II 550 - 2g ram > PSDR v2.0.0 Beta SVN 3706 - Firmware 2.0.1.1 - Driver version > 3.5.2.8028 - Pal version 3.5.2.8028 > > Les VK2DSG > _______________________________________________ > Flexedge mailing list > [email protected] > http://mail.flex-radio.biz/mailman/listinfo/flexedge_flex-radio.biz > This is the FlexRadio Systems e-mail Reflector called FlexEdge.
