Hi,
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
dd if=pctv4XXe.sys of=dvb-ttusb2-a.raw bs=8 skip=22287 count=1390
dd if=pctv4XXe.sys of=dvb-ttusb2-b.raw bs=8 skip=23682 count=1408
dd if=pctv4XXe.sys of=dvb-usb-pctv-400e-01.raw bs=8 skip=25093 count=1315
dd if=pctv4XXe.sys of=dvb-ttusb2-c.raw bs=8 skip=26411 count=1232
dd if=pctv4XXe.sys of=dvb-ttusb2-d.raw bs=8 skip=27646 count=1326
dd if=pctv4XXe.sys of=dvb-ttusb2-e.raw bs=8 skip=28975 count=1378
dd if=pctv4XXe.sys of=dvb-usb-pctv-450e-01.raw bs=8 skip=30356 count=1323
dd if=pctv4XXe.sys of=dvb-usb-pctv-452e-01.raw bs=8 skip=31682 count=1375

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.
