Are there any messages like these in > /var/log/messages? Thank you for pointing those out, I've checked my system and ruled out all your mentioned causes. The vdr is on top all the time, top shows 0-0.5% cpu utilization, even when I do 2-3 recordings at the same time. I've disabled time setting in VDR from sat stream, the system is set to sync time using ntp. So those are not the problems here. I'm trying to figure out why starting recording on budget card would fix this lagged behavior on FF card. Its like something flushes/clears the data pipe to FF card when I start recording on budget card, the FF card starts to respond very fast and without pauses. I guess the issue is specific to my setup only, possibly an issue with PCI bus transfers. I'm going to try to move my FF card to another system and see how it behaves there.
