1. Get source code like described here:
http://linuxtv.org/wiki/index.php/How_to_Obtain,_Build_and_Install_V4L-
DVB_Device_Drivers#Using_Mercurial

2. Edit the file v4l-dvb/linux/drivers/media/video/cx88/cx88-dvb.c
- search for CX88_BOARD_HAUPPAUGE_HVR1300 (somewhere around line 1470 )
- change the lines that they look like:

	switch (core->boardnr) {
	case CX88_BOARD_HAUPPAUGE_HVR1300:
		/* We arrive here with either the cx23416 or the cx22702
		 * on the bus. Take the bus from the cx23416 and enable the
		 * cx22702 demod
		 */
		/* Toggle reset on cx22702 leaving i2c active */
		cx_set(MO_GP0_IO, 0x00000080);
		//udelay(1000);
		//cx_clear(MO_GP0_IO, 0x00000080);
		//udelay(50);
		//cx_set(MO_GP0_IO, 0x00000080);
		//udelay(1000);
		/* enable the cx22702 pins */
		cx_clear(MO_GP0_IO, 0x00000004);
		udelay(1000);
		break;


3. then go on like described in the wikipage how to build and install. Maybe you have to disable firedtv card in the config by first doing a "make menuconfig" and disable it there.

Bug description:
This is a continuation of bug #436564. Please refer to that for relevant dmesg'.
The capture card I have is the Hauppauge HVR-1300.
The card is now correctly recognized as DVB-T but channel scan fails with message "Timed out, no signal" at each channel is scanned.
The command scan <location> > channels.conf ends correcly and file channels.conf is feeded with all tunable channels.
I tried to import such channels.conf with the same result.
Increasing the signal and channel timeout in the DVB settings (now up to 1000 but I planned to increase to ignore) doesnt solve the problem.
Tonight I will try what Marc suggested - mythtv-setup --verbose channelscan,siparser,channel,record - then I will report the log.
