[RFC PATCH] Getting Hauppauge WinTV HVR-1400 (XC3028L) to work

[Alina Friedrichsen]

With this patch my DVB-T receiver works now like before 2.6.34, only the
first four tunings fails, after that all works fine.
The code was still in there, only commented out. As the original author
says, please test it with different XC3028 hardware. If no one has problems
with it, please commit it.

This is problematic, as it seems to be country-specific and/or demod-specific. 
We'll need to work on a different solution for it. On what Country do you live?
By looking at HVR1400 entry, it uses a dibcom 7000p demod.
We need to know what are country/demod for the users for whose the old code
were broken.

Cheers,
Mauro

I live in Germany. In which country, with which hardware does the old code work, and the new not?

Old code:

if (priv->cur_fw.type & DTV7)
	offset += 500000;


New code:

if (priv->firm_version < 0x0302) {
	if (priv->cur_fw.type & DTV7)
		offset += 500000;
} else {
	if (priv->cur_fw.type & DTV7)
		offset -= 300000;
	else if (type != ATSC) /* DVB @6MHz, DTV 8 and DTV 7/8 */
		offset += 200000;
}

Cheers,
Alina

Can you suggest an other solution?
