But judging from what I saw the last time I used it (which is 2-3 years ago), our projects have different scopes. Mine is expected to work like this: frontend.conf: -- FRONTEND /dev/dvb/adapter0/frontend0 FREQUENCY 12421000 POLARIZATION H SYMBOL_RATE 27500000 -- (Will be switched to XML later...) devices.xml: -- <?xml version="1.0" encoding="iso-8859-1"?> <device-list> <device> <demux>/dev/dvb/adapter0/demux0</demux> <dvr>/dev/dvb/adapter0/dvr0</dvr> <frontend>/dev/dvb/adapter0/frontend0</frontend> </device> ... -- programs.xml: -- <?xml version="1.0" encoding="iso-8859-1"?> <program-list> <program> <program-name>Das Erste</program-name> <destination><ip>239.192.1.1</ip></destination> </program> ... -- TCP CLI: -- jonny@dh3mb ~/projects/dvbstreamd $ telnet localhost 3333 Trying 127.0.0.1...

Moreover, an old version (without the CLI and XML style files) of my project runs fine on a Pentium III Xeon 800 MHz with 4 DVB boards multicasting a total of >100 MBit/s. This old version has been running stable for years, but it's also a bit of an hack, so I'm doing a complete rewrite now, which is aimed to still be more efficient (maybe 4 PCI DVB boards und 4 USB DVB boards are possible on recent hardware?). I'm already using epoll() instead of poll(), and maybe using splice() is possible, this is why I'm asking...
