[QUOTE="mrdutchpl, post: 84824, member: 188962"] people, thanks for all the answers but I don't think you understand my problem, nor the full DVB system. A transponder / single satellite frequency transmits at a certain bitrate, close to 4-5 MByte/sec. The simplified calculation is as follows: symbolrate = 22-27 MSymbol / sec. Using QPSK modulation (= two bits per symbol) = 44-54 MBit/sec. Reduce this by the FEC (error correction) overhead and divide by 8 and you have the 4-5 MByte/sec. Again, this contains multiple A/V streams. A single A/V stream can be between 4-6 MBit/sec, depending on the broadcast quality. What I want is the transport stream at full rate, as is received from the tuner by the demux. After the demux, a part of that stream (Audio + video PID) is written to disk. Maybe I need to do some development myself... ?. [/QUOTE]
