I dont know what you did to 'manually add it to the build' ... but the 
correct method is as follows:

make cx88-ivtv  (will symlink it into the build, and cause it to be 
installed with the other modules)
make
make install

In the newer tree, this firmware file has been renamed to the standard 
cx23416 encoder firmware image filename, "v4l-cx2341x-enc.fw"   -- The 
cx88-blackbird driver, pvrusb2 driver, and ivtv drivers all use the same 
firmware image for the encoder.  Ask google where to find it -- google 
knows ;-)

yikes!  I would recommend the extraction scripts found in the ivtv 
driver, or use fwextract.pl from the pvrusb2 standalone driver.  Also, 
your distro might have the firmware available in a package...

Based on the code in Steve's tree:

--- a/linux/drivers/media/video/cx88/cx88-input.c	Mon Mar 13 13:17:11 2006 -0300
+++ b/linux/drivers/media/video/cx88/cx88-input.c	Mon Mar 13 22:20:58 2006 -0400
(at)  (at)  -173,6 +173,9  (at)  (at)  int cx88_ir_init(struct cx88_core *core,
		ir_codes = ir_codes_hauppauge_new;
		ir_type = IR_TYPE_RC5;
		ir->sampling = 1;
+		break;
+	case CX88_BOARD_HAUPPAUGE_HVR1300:
+		/* fixme: enable HVR1300 support */
		break;
	case CX88_BOARD_WINFAST2000XP_EXPERT:
		ir_codes = ir_codes_winfast;


No, the remote control is not yet supported.

Use the newer tree -- the cx8802 spam has been silenced in master 
repository, but Steve's tree is 7 weeks old, and was never merged into 
master.  You might have to play around a bit....  Perhaps you'll need to 
do something like this...

hg clone http://linuxtv.org/hg/~stoth/v4l-dvb
cd v4l-dvb
hg pull http://linuxtv.org/hg/v4l-dvb
hg update

(resolve any conflicts... you MIGHT have to do 'hg update -m' ... hg 
will let you know if necessary)

If the merge doesnt work for you, then you will have to read a bit of 
the mercurial documentation... until Steve updates his tree.  I haven't 
tried this using Steve's tree myself, so I cannot say whether it will 
merge cleanly or not, but it is worth a try.

Good Luck, and I hope this helps.
