[linux-dvb] Re: Tuning problems with the refactored drivers

First it tuned pretty badly. (Only 30 channels or so found) but after

started to tune channels very well.
Now it can even find channels from out national tv channel! So maybe the
mdelay-line should also be added in the
CVS? (mdelay(50) got removed when you removed that hack)
ves1820_writereg(state, 0x00, reg0 & 0xfe);
ves1820_writereg(state, 0x00, reg0 | 0x01);
mdelay(200); //
this is the new line!
Does setting the dvb_override_tune_delay parameter to 200 have the same effect
as doing this? Its just that there is a mechanism defined for solving exactly
this problem which I would prefer to use rather than putting an mdelay in the
frontend itself.
If I remember correctly this delay was only required for a few
particular demods, thus the demod driver should be the better place...
