Hello Bert I raised the same question two weeks ago, I only got an offline answer, see below.$ I hope to get some more replies too.
------------------------------------------------------------------------------ I wanted to know if the Digital Devices DuoFlex CT PCIe TWIN Combo DVB-C DVB-T card is supported. This card has 2 Ports, using one PCIe slot. Additionally it can be extended by 2 tuners to a total of 4 tuners, still using only one PCIe slot. There is also a Octopus version who is able to run 8 tuners using only one PCIe slot. Is this card supported, is it performing well with 2/4 tuners ? Will it be able to stream 4 HD channels at once via one PCIe slot ? currently there is no support for it, might not sound too popular but we have USB based DVB-C tuners which can be used with PCIe based USB extenders. So far we tested 3 tuners on a Notebook with 1.3 ghz streaming the entire bouquet (each around 50 Mbit). HDTV usually requires 15 Mbit SDTV 4-8 Mbit. So this is not only related to 4 HD channels but to the entire Bouquet (which could be up to 3 HD Streams for DVB-C). Additionally those devices support Hardware PID filtering in order to lower the bandwidth, virtually any amount of devices can be attached until the USB Bandwidth for one controller let's say 300-400 mbit is fully utilized. The software is hotplug aware and well tested on x86, ARM, MIPS, PPC (some architectures support little/big endian). The drivers are in userspace, although there's an opensource kernel acceleration module available which can lower the cpu usage (this one only has around 500 lines of clean written code which is also very stable, it's mostly used with low powered embedded devices). If you have any further question about this just let me know. This mail is not intended to be on the mailinglist since it's slightly offtopic of your initial mail request. Best Regards, xxxxxxxx I hope to get some replies from people using this card.
