OK, I think what's wrong here. It's an msp3400 bug. Address 0x200 does
not exist on a MSP3415D chip.
If you can compile the kernel, then edit drivers/media/video/msp3400.c.
If you are using the msp3400.c from ivtv, then edit that source.
In both cases go to the function autodetect_stereo(). That function
contains a switch. Now remove the whole MSP_MODE_BTSC case. So this:
break;
case MSP_MODE_BTSC:
val = msp3400c_read(client, I2C_MSP3400C_DEM, 0x200);
msp3400_dbg("status=0x%x (pri=%s, sec=%s, %s%s%s)\n",
val,
(val & 0x0002) ? "no" : "yes",
(val & 0x0004) ? "no" : "yes",
(val & 0x0040) ? "stereo" : "mono",
(val & 0x0080) ? ", nicam 2nd mono" : "",
(val & 0x0100) ? ", bilingual/SAP" : "");
rxsubchans = V4L2_TUNER_SUB_MONO;
if (val & 0x0040) rxsubchans |= V4L2_TUNER_SUB_STEREO;
if (val & 0x0100) rxsubchans |= V4L2_TUNER_SUB_LANG1;
break;
}
if (rxsubchans != msp->rxsubchans) {
becomes this:
break;
}
if (rxsubchans != msp->rxsubchans) {
Please let me know ASAP if this fixes your problems. If it does, then
I'll try to get it in 2.6.16 before it is released. It is already fixed
for 2.6.17 in any case (I did a lot of rewriting for msp3400.c).
Although I do have a WinTV card with a msp3415d I never noticed this as
it is NTSC specific. This code is never reached in PAL.

Hans
