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.
