I've been using ProgDVB for a while now to watch channels using my USB DVB-T dongle. I've recently had this really annoying problem that i can't find a way around.
ProgDVB stopped receiving all channels and stations. I could select the channel from the window on the left but no video or sound came through. The signal strength meter was at 100% and the quality didn't show a number at all (usually 30-60%).
I decided to delete all the channels from the list and search for channels again. It scanned in half a second (usually nowhere near that quick) and picked no channels up at all.
I decided to un-install the software and install the newer 6.02.01 version which did the same. I then un-installed the driver (Device Manager -> Un-install "Intel CE9500 DVB-T Receiver"), unplugged it, restarted and plugged it back in again. Windows found it, installed it and everything was still the same. I also tried installing the drivers off the CD again.
I also tried using "set devmgr_show_nonpresent_devices=1" in command prompt and show hidden devices in Device manager and removed any DVB looking bits such as "BDA IPSink" and "BDA Slip De-framer".
I also have tried BlazeDTV which came with the DVB-T receiver. It did the same; incredibly fast scanning with 100% Strength and 0% Quality.
I have tried the receiver in my laptop which worked on BlazeDTV so that rules out it being faulty. I usually run it through a powered USB hub but it didn't work plugged straight into the computer either.
The only major thing i've done recently is enable my motherboard's on-board audio (AC97) and run it along side my Creative Audigy so i've got 2 separate sound out put (won't bore you with the reason why). I've tried un-installing the AC97 driver and disabling it again in the BIOS but no difference. I guess it's driver issue.
I'm out of ideas and would appreciate any help.
