Trying to get a Kworld-ATSC110 working

[maillist <maillist (at) boilerbots.com>]

Ok, I got the ATSC working and can watch HD programs and the regular 
NTSC is also working but it is not quite right.

Here is the problem I have.

I load module  "saa7134 tuner=68"

and I see the message:

Feb 12 03:37:40 ford kernel: ACPI: PCI Interrupt 0000:01:06.0[A] -> Link

Feb 12 03:37:40 ford kernel: saa7133[0]: registered device vbi0

Then I load "saa7134-dvb" and get the following:

Feb 12 03:37:46 ford kernel: nxt200x: NXT2004 Detected
Feb 12 03:37:46 ford kernel: DVB: registering new adapter (saa7133[0]).
Feb 12 03:37:46 ford kernel: DVB: registering frontend 0 (Nextwave 
NXT200X VSB/QAM frontend)...

The firmware will not be loaded to the nxt2004 until I try to access the 
device. So I run azap and it caused the following:

Feb 12 03:38:14 ford kernel: nxt2004: Waiting for firmware upload 
(dvb-fe-nxt2004.fw)...
Feb 12 03:38:14 ford udevd[1279]: move seq 3634 with timeout 10 to exec

Feb 12 03:38:14 ford kernel: nxt2004: Waiting for firmware upload(2)...
Feb 12 03:38:16 ford kernel: nxt2004: Firmware upload complete

After the nxt2004 firmware has been loaded I can finally load then 
"tuner" module. If I am lucky I will see the following:

Feb 12 03:38:25 ford kernel: tuner 0-0061: I2C RECV = 74 74 74 74 74 74 
74 74 74 74 74 74 74 74 74 74

Feb 12 03:38:25 ford kernel: tuner 0-0061: Calling set_type_addr for 
type=68, addr=0xff, mode=0x04
Feb 12 03:38:25 ford kernel: tuner 0-0061: tuner 0x61: called during 
i2c_client register by adapter's attach_inform
Feb 12 03:38:25 ford kernel: tuner 0-0061: type set to 68 (Philips 
TUV1236D ATSC/NTSC dual in)
Feb 12 03:38:25 ford kernel: tuner 0-0061: saa7133[0] tuner I2C addr 
0xc2 with type 68 used for 0x0e


Sometimes it doesn't do anything when the tuner module loads. Then I 
re-run azap, maybe mplayer then stop the ATSC stream and reload the 
tuner module again. Anybody got any suggestions?

A secondary problem is that the tuv1236D is a dual input tuner module. 
It has an input for the HDTV and a seperate input for standard NTSC. 
Currently, the driver always uses the HDTV input for everything. I would 
like the inputs to switch as it was designed because I use my antenna to 
receive local chanels in HD and cable for all other cable channels. 
Anybody working on a solution for this?

One last thing.....what do I do with the changes that at least make it 
possible to use the Kworld card?
