We have wrong take-over frequencies up to bttv-0.7.87.
These channels are:
{ "SE7", 147250 }, \
{ "SE8", 154250 }, \
{ "SE9", 161250 }, \
{ "SE10", 168250 }, \
The entries for tuner=1 are wrong (140.25/463.25), this
patch corrects these to 170/450 per datasheets FM1246(PAL_I)
and FM1216 (PAL_BG)!
Try appended patch and report.

P.S. There are more errors in tuner.c, e.g. tuner=5 on SE10 with
takeover 168.25 would select MID BAND=VHF_H by this comparison:
if (freq < tun->thresh1)
config = tun->VHF_L;
else if (freq < tun->thresh2)
config = tun->VHF_H;
else
config = tun->UHF;
But datasheet mandates LOW BAND. Expect a fix later.
