[linux-dvb] FE_HAS_LOCK but no signal

i am having problems getting data from my STB

i am using Mythdora as my distro so, i believe this is basically Fedora
Core 5 with MythTV-0.20 included (and various other required packages).

i have a Hauppauge DEC2000 stb which i am trying to use within mythtv.
the correct firmware is in /lib/firmware and from dmesg i can see the
adapter and frontend are both registered.

i can successfully ./scan for available channels and have produced my
channels.conf file. when i ./tzap i get the following:

[root at mythtv_linux ~]# tzap -r "BBC TWO"
using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0'
tuning to 641833330 Hz
video pid 0x0262, audio pid 0x0263
status 00 | signal 0000 | snr 0000 | ber 00000000 | unc 009c645e |
status 1f | signal 0000 | snr 0000 | ber 00000000 | unc 009c645e |
FE_HAS_LOCK
status 1f | signal 0000 | snr 0000 | ber 00000000 | unc 009c645e |
FE_HAS_LOCK
status 1f | signal 0000 | snr 0000 | ber 00000000 | unc 009c645e |
FE_HAS_LOCK
status 1f | signal 0000 | snr 0000 | ber 00000000 | unc 009c645e |
FE_HAS_LOCK

if i pick different channels the frequency an pids change but i always
get signal 0000 and a lock. if i try and capture stream using the following:

cat /dev/dvb/adapter0/dvr0 > myvideo.mpg

i get a file of zero bytes. if i try and use mplayer or xine they both
fail too. since this is a stb also i can play a scart cable into it and
i do see that the channels are being changed when i tzap  but i just
dont seem to be getting any data back from the stb.

does anyone have any ideas?
