Hi!
(I guess the forums are not the best place to post this, hence
reposted here...)
By accident I stumbled across the special case for TT-budget S2-3200
(DVB-S/DVB-S2) in vdr's dvbdevice.c, and since both my tuners using
the pctv452e driver have the same issue (which are STB0899 too,
issue is the red/yellow/green bars in femon/osd didn't appear)
I added an OPTION to the FreeBSD port (STB0899_SIGNAL in the port's
make config menu) to enable the patch below. Optional since I don't
know if there are STB0899-based tuners that don't have the problem,
does anyone here know? (see log, if vdr logs like
vdr: [29376960] frontend 0/0 provides DVB-S,DVB-S2,DSS with QPSK ("STB0899 Multistandard")
and the bars appear without the patch please let us know, noting
pci ids for the cards especially if different from 0x13c2:0x1019
or if it's usb, thanx!)
Cheers,
Juergen
And here comes the patch, also at:

Maybe I'm missing something here, but why don't you just add the subsystem id of your card
to the switch statements?
