I have the same card but it worked fine after i compiled a vanilla 2.6.12. It might be worth you posting which kernel version you used and your .config

| Post subject: | wintv nova t wont scan |
Im trying to get a wintv nova-t pci card working with knoppmyth in northern ireland (uk )... its detected as cx88[0]: subsystem: 0070:9002, board: Hauppauge Nova-T DVB-T [card=18,autodetected] cx88[0]: hauppauge eeprom: model=90002, tuner=76 here is the story so far 1) tried the card under windows which seems to work fine - seems to rule out a faulty card 2) wont scan for channels with mythth-setup or 3) wont scan with dvbscan and my hand crafted config file for northern ireland to keep this post a bit smaller i have put the outputs /logs on a web server dvbscan -5 ni-Divis (output from dvbsan) and mythtv-setup output output from dvbscan captured from an xterm and and dmesg output dmesg output and my hand crafted dvbscan file for northern ireland got these figures from a friends working set top box (not myth based just a regular one) anyone any ideas ? thanks in advance ps i had asked this question under the installation forum - but the thread seems to have been deleted - not really sure why tho as i was pretty sure the discussion related to installation (as in i cant get the card installed - i assume its a configuration issue - so maybe this does not classify as installation ?) EDIT: pps - after reading a few other forums i now understand that the problems i am experiencing are regarded as 'post installation' - i suppose its a matter of terminology but i had imagined that installation refered to the phase before you got it working ! I'm now fully with it however. and wont post in that forum again. |

after some more googling it would appear that mytv seems to have problems with some/all motherboards based on kt133 chipsets...... Im using an Abit KT7a with just such a chipset - could this be part/all of my problems ? Is it a lost cause - should i just ditch it and try and get a 2nd hand mobo from ebay ? (dont want to sink alot of cash into this project if i cant get it working!) Is there anything else is should try bios/boot param wise ? Declan |

word on the street back when those were popular was that the problem was actually a dma bug in the chipset, and I never heard of anyone getting around it. I know I had one too and I ended up switching to an nforce2 based motherboard at the time. |

I just remembered one other problem I had with my DVB card. I had to re-build the kernel to get it to work because there was a bug in the kernel for my card. However, not only did I need to rebuild the kernel but I also needed to enable an option that was not enabled in cesman's kernel. The option is Device Drivers->Multimedia Devices->Video for Linux->DVB Support for CX2388x Based TV Cards. There was also one other DVB option that wasn't checked, so you might want to try setting that one too and rebuild your kernel. The chipset thing is something I would worry about later and is almost certainly not the problem you are having with your nova-t card. |

is there a recipe for rebuilding the kernel for dvb - i had assumed knoppmyth supported the wintv nota-t (90002) |

Any of the kernel building recipes will do. The important thing is to ensure that you configure the kernel with the right options. DVB is in heavy development and occasionally things are reorganised. That is how my card got broken (and why I needed to patch the kernel to get it to work until 2.6.13-rc4). Perhaps something was reorganised so that it needs to be selected as a module?? Im just guessing, but it's worth a try before giving up. If that turns out to be the problem, i'm sure cesman will listen to your kernel configuration requirements for the next version of knoppmyth. |

A small update on this - not a solution yet but some progress in the right direction : I tried a kernel rebuild patching for video4linux (loosely following the instructions at http://www.helkit.com/cgi-bin/twiki/bin ... exantNotes) To my as astonishment both dvbscan and the mytv-setup will now both scan and find about 25+ channels... However the joy ends there ... 1) cant see how to populate the tv listing based on the channel scan ... am i missing something obvious... 2) cant get the card to display any picture ... just back screen - even after choosing a 'start channel' I've tried testing the card using tzap "Sky News" followed by dvbstream piped to mplayer ... but no joy here either ... screen momentarily flashes but no picture hopefully my new '2nd hand' motherboard from ebay should arrive next week and i can start all over again with new hardware and new problems! I'm not having an easy time with this current setup.. |

With my card, once I got over the channel scan hurdle (and it was quite significant back on R4V5. still is with R5A16) everything just worked. What does your backend log file say when you attempt to watch live tv? Have you attempted to do a manually scheduled recording? |

kernel version before patch = 2.6.11.9-chw-2 (knoppmyth std) kernel version after = 2.6.11.9-chw-2-kraxel2 I'm waiting on a 'new' motherboard from ebay this week - which is non via and im more hopefull it will be less problematic. I'm sorta tempted to try a build based on mandrake + the mythtv-suite as opposed to knoppmyth to see if it would work ok with my hardware, but dunno if its worth the effort I'd love to know if KnoppMyth R5A16 normally supports the wintv-nova (pci - 90002) and have i just been unlucky with my hardware. |

do you have a link for instructions to build 2.6.12 ? |

It's quite easy once you know how sorry if this is too detailed but here u go...
change to the src folder: Code: cd /usr/src download the either the latest 2.6.12 Code: wget http://www.kernel.org/pub/linux/kernel/v2.6/linux-2.6.12.6.tar.bz2 or 2.6.13 Code: wget http://www.kernel.org/pub/linux/kernel/v2.6/linux-2.6.13.tar.bz2 unzip it Code: tar xvjf linux-2.6.12.6.tar.bz2 Remove the link to the old kernel source Code: rm linux Link the new source Code: ln -s linux-2.6.12.6 linux load menuconfig Code: cd linux make menuconfig drill down to: device drivers --> multimedia devices --> video for linux Make sure "Connexant 2388x ..." & "DVB support for cx2388x..." are selected <M> In fact, you probably want everything under Video for linux & Digital Video Broadcasting Devices & any sub sections selected <M> Once you've done that, completely exit & when it says "Do you wish to save your new kernel conf..." select yes to compile and install the new kernel Code: make make modules_install make install You then need to run lilo and reboot (you may also need to edit lilo.conf first) After the reboot, check it is running the new kernel Code: cat /proc/version
Linux version 2.6.12 (root@mythtvbox) (gcc version 3.3.5 (Debian 1:3.3.5-12)) #2 Sun Aug 14 00:41:31 BST 2005 Now I've just knocked that out from memory, the only bit i'm unsure of is if you need to edit lilo.conf... |

Thanks for that - looks mostly familar with the exception of wget. |

ok , got new case and ebay mobo today... rebuilt the box in a prettier case (coolermaster atcs 620) and its rebuilding the kernel as per instructions as we speak. |
