The build firmware downloads the latest version of the firmwares from: http://www.linuxtv.org/downloads/firmware/ It should be noticed that the install procedure won't fail if you never downloaded the firmwares, due to the "-" signal.

If you're willing to fix those distro-specific stuff, on Fedora 15, the 3.0 kernel were renamed as "2.40", as they wanted to avoid touching on some scripts (that's what I got from a lwn discussion). Maybe other distros might have done weird things like that. The only practical consequence I noticed with F15 is that one driver were disabled (the firewire one). > The last issue I have is that the media.ko module isn't installed when I run > 'make install'. I tried to fix it, but I got lost in the Makefile/perl magic :-) That's weird... I took a look here. My Makefile.media was generated with a line to install it. See: @n=0;for i in dvb-ttpci.ko budget-patch.ko ttpci-eeprom.ko budget-av.ko budget.ko budget-core.ko budget-ci.ko;do if [ -f "$$i" ]; then if [ $$n -eq 0 ]; then echo -n " dvb/ttpci/: "; install -d $(DESTDIR)$(KDIR26)/dvb/ttpci; fi; n=$$(($$n+1)); if [ $$n -eq 4 ]; then echo; echo -n " "; n=1; fi; echo -n "$$i "; install -m 644 -c $$i $(DESTDIR)$(KDIR26)/dvb/ttpci; fi; done; if [ $$n -ne 0 ]; then echo; strip --strip-debug $(DESTDIR)$(KDIR26)/dvb/ttpci/*.ko; fi; @n=0;for i in media.ko;do if [ -f "$$i" ]; then if [ $$n -eq 0 ]; then echo -n " ../linux/drivers/media/: "; insta ll -d $(DESTDIR)$(KDIR26)/../linux/drivers/media; fi; n=$$(($$n+1)); if [ $$n -eq 4 ]; then echo; echo -n " "; n=1; f i; echo -n "$$i "; install -m 644 -c $$i $(DESTDIR)$(KDIR26)/../linux/drivers/media; fi; done; if [ $$n -ne 0 ]; then echo; stri p --strip-debug $(DESTDIR)$(KDIR26)/../linux/drivers/media/*.ko; fi; For me, it is likely a trouble at scripts/make_makefile.pl, on that line of the script: $idir =~ s|^../linux/drivers/media/||; An one line patch to make the last / optional is probably enough to fix it.
