Hi there, in the last days I come accross a strange phenomen: One vdr thread eats up to 45% cpu on my Pentium3 700Mhz system when I did nothing with my vdr except live viewing on a ff card without transfer mode. Some digging resulted in this: - The thread is the section handler thread. - The cpu-load depends on the transponder currently watching on. The Pro7/Sat1 Transponder was the one with the highest load. Worst case is to record Pro7 and watch it live at the same moment: Recording goes over the second card resulting in 2 section handler threads, one for each card eating whole cpu. Attached is a Patch to simply add one sleep(1) inte the loop before the poll. This results in reducing the cpu-load from 45% to 1.3%. And it does not seem to lose any sections. If you need more data to reproduce this: I have a gentoo system without nptl using the newest cvs dvb driver. The system itself has a FF 1.3 card and a skystar 2.6B card.
