Well, I did an apt-get upgrade on my Ubuntu 6.10 based mythtv box. It upgraded the kernel for me. This always provides a problem with the IVTV drivers which provide support for my Hauppaugh capture card. This means that I have to recompile them and reinstall.
Usually, for good measure, I download the latest driver for my kernel. Since the update to Dapper Drake kept me at 2.6.15 (upgrade to -28 from -27), I downloaded the 0.4.10 driver.
I also had to rebuild my build environment so that I could recompile and reinstall the driver. I just follow section 5 off of Hyam’s website regarding a MythTV 0.19 install on a Breezy Badger box. It is a little out of date, however, this section is still very relevant.
