I wanted to report that I have version 3.1 of the TechniSat AirStar-HD5000-PCI working! My base distribution is FC3. I downloaded kernel 2.6.13.2 from kernel.org, patched with the hd5000.patch and did make oldconfig based on the redhat fc3 .config. Everything complied and installed fine. The patch complained a bit, but the complaints were of no consequence. The one hunk that failed was a change made in a comment block so it didn't matter. Here is the output: [root@localhost src]# patch -p0 < hd5000.patch patching file linux/drivers/media/dvb/b2c2/flexcop-fe-tuner.c Hunk #1 succeeded at 13 with fuzz 2.

At this stage, I followed the instructions in: http://www.rsmas.miami.edu/personal/angel/mythtv/air2pc-howto.html (Except for the step about nxt-2002 firmware. That is not needed) Thanks to the developers!
