[linux-dvb] Re: Hauppauge DEC2000-t (Germany) tuning question

[Michael Loose <m.loose@arcor.de>]

k, new luck. 

You may find this interesting:

- changed the firmware in /etc/dvb to 215a
- recompiled/reinstalled the whole stuff

While my last tries before doing so the box locked up at an unknown
point (the remote control just allowed turning on/off the box, but no 
channel tuning or changing the sound volume. Powering off the box did
not fix this - i thought of a hardware defect because the remote control
had fallen down badly short time before...)  

To verify that something is broken i rebooted in Win98.
Hauppauges Software moaned about an "application error". I unpowered
the box for a while, rebooted in Win again and was able to tune 
channels. From this point of time on the remote worked again.

I left the whole thing running (output to TV at the same time) and
rebooted in Linux. 
 
During boot the box locked up again (frozen,  still-picture on TV, no
sound) 

output of dmesg after boot:

"usb.c: USB disconnect on device 00:1d.0-1 address 3
 hub.c: new USB device 00:1d.0-1, assigned address 4
 DVB: registering new adapter (DEC2000-t).
 DVB: registering frontend 0:0 (TechnoTrend/Hauppauge DEC2000-t Frontend)..."

Calling tzap wouldn't reboot the box.

output of dmesg after first try:

"DVB: registering frontend 0:0 (TechnoTrend/Hauppauge DEC2000-t Frontend)...

At this point of development i'm kinda happy that there is some kind 
of interaction, 

Btw, i updated the box - firmware using the over-the-air function last
week.


Cheers
