I extracted firmware for DVB-S Pinnacle PCTV Sat Pro USB (450e) from file on installation cd:
/mnt/cdrom0/Driver/PCTV 4XXe/pctv4XXe.sys
I placed it also on my site:
http://www.natur.cuni.cz/~repko/fw/pctv4XXe.sys
because Pinnacle has some new driver, which I haven't tried yet:
http://cdn.pinnaclesys.com/SupportFiles/PCTV%20Drivers/PCTV%20400e,%20450e,%20452e/XP32.ZIP
#!/bin/bash

for i in *.raw; do
j=$(echo $i | sed s/raw/fw/)
./convert $i $j
rm $i
done
where "convert" is compiled (gcc convert.c -o convert) from following "convert.c":
#include <stdio.h>
int main (int argc, char *argv[])
{
FILE *raw, *fw;
unsigned char buf[22];
int n;
raw = fopen (argv[1], "r");
fw = fopen (argv[2], "w");
while (fread (buf, 1, 22, raw) == 22) {
fwrite (buf, 1, 1, fw);
n = buf[0];
buf[n+5] = 0xff;
fwrite (&buf[2], 1, n+4, fw);
}
fclose (raw);
fclose (fw);
return 0;
}
There are also some "TechnoTrend TT-USB2" firmwares, which were not usable with my hardware. Created dvb-usb-pctv-450e-01.fw is identical to already used firmware. I copied dvb-usb-pctv-450e-01.fw to /lib/firmware/dvb-usb-pctv-400e-01.fw and it was uploaded and worked correctly.
