Another computer (AMD Geode NX1750 and a laptop = harddrive, the 480W Antec is very very bored) gives the same result. My = regular computer was turned off when I tested that. The patch made no = difference whatsoever. The Xcam is actually not picky at all, it is well = known for working in pretty much any receiver - and it does. For = example, KNC1 CI's are quite picky but the Xcam has no problems with = that. Even the Matrix Reborn won't run in a KNC1, yet the Xcam does. I installed the card on Windows to test a bit. I also noted the CI works = better on Linux when I fold the CI cable in tinfoil. Here's an overview = of some tests: *Windows, unshielded 40cm cable: Xcam sometimes takes a while to init, but works on all tested channels = after that (including RTL4 and RTL5). Matrix Reborn: similar result. *Linux, v4l-dvb from hg april 12, 40cm cable in tinfoil: Xcam does init and works. But RTL4, RTL5 = (http://nl.kingofsat.net/pack-canaldigitaal.php) give only sound. The = videoPID is correct and I did a rescan. Audio is gone if I remove the = CAM, so it is encrypted. Matrix similar result, no picture on RTL4 and RTL5 here either, but = apart from that it seems to work. *Linux, v4l-dvb from hg april 12, unshielded 40cm cable: Xcam does not init anymore. Not at all. Just "Invalid PC card inserted :(". Matrix Reborn does init, but init fails sometimes as well. When it does = init, I can watch most channels.. But not RTL4 or RTL5 (only sound). SCM Conax 4.00e: init sometimes, but can't even get into the menu. Don't = have a Conax subscription card right now. RTL4 and RTL5 do work on Windows or a standalone receiver with CI. I = also tried to disable all the power in the house and did a test with = UPS, but the Xcam still would not init with the unshielded cable. So no = electrical devices in the house went bad. The UPS or display are not the = source either, tried unplugging them. And a S-1500, T-1500 and S2-3200 = are all doing the same thing. I've also got a Aston 1.05 and official = Mediaguard CAM to test if required.
