I dont have an answer for you, but I'll give you somewhere to look.
udev is responsible for building /dev/dvb nodes so It apears to be a udev issue, look into MKDEV or MAKEDEV cant rem the exact name of the script. |

If it worked with the old device, it is probably not an udev issue. More likely your kernel is not configured correctly (maybe missing tuner/frontend support) or the device requires different firmware. (Unfiltered) dmesg usually has more information. |

jepp i think it is à frontend thing to. the old card
was for mpeg 2 and this is for 4 as i understand
it .but i dont understand what /dev/dvb has to do
with it.correct me, if udev see it it should be in dev.
my old card Did not have à frontend in dev ,there were
only /dev/dvb/device0 .i have read the gentoo vdr doc
and the budget cards wont have to have more then just
the kernel stuff.it can be à to old kernel (2.6.31)so i am
on to update but got some problem with(2.6.35) i hope that
is the problem |

The /dev/dvb device will only appear if the kernel has the correct driver for chipset/frontend/tuner and firmware is installed.
If the /dev/dvb device does not appear, this usually means that one of those is missing. |

I thought I made myself clear already.
- Find out the correct chipset driver.
- Find out the correct tuner driver (if any).
- Find out the correct frontend driver (if any).
- Find out the correct firmware.
And verify with lspci -k (kernel driver in use) and dmesg that these things are loaded correctly. If you post here, then give unfiltered output. |

okej i have looked for some answers and did not come up to any ting.
from what i have find from the install guide is the same as in the gentoo-sources
so how do i make it work.
select the device/card-drivers to compile and install
# make menuconfig
follow the menus and enable at least
<M> Technisat/B2C2 FlexCopII(b) and FlexCopIII adapters
<M> Technisat/B2C2 Air/Sky/Cable2PC PCI
<M> Technisat/B2C2 Air/Sky/Cable2PC USB
4) Install firmware binary
The CX24120 requires a firmware to operate normally. The file is called "dvb-fe-cx24120-1.20.58.2.fw" and has to be put into the system's firmware directory.
/usr/lib/hotplug/firmware
or
/lib/firmware
for example you can do:
# cp <path-to-binary-file>/dvb-fe-cx24120-1.20.58.2.fw /usr/lib/hotplug/firmware |

Don't know if this is still an issuer but here is something that looks like a resolution:
http://linuxtv.org/wiki/index.php/TechniSat_SkyStar_S2
And: TechniSat SkyStar S2 != TechniSat SkyStar HD2. So the mantis-stuff posted above will not work! |

If its anything like my TV card you have to build them as modules, if i build them built in i don't see anything _________________ I know 43 ways to kill with a SKITTLE, so taste my rainbow bitch. |

I can send you patch if you still need it. |
