Just set up PROGDVB 6.06.01. I am using a Twinhan 1034 with the device set as DTV-DVB Mantis DVBS BDA Receiver. Everything set up OK, all channels are available but, when I change channel I get a blank screen but if I then click on Settings/Options and then OK the channel appears. Any idea why ??

Is it free channels?
Try start ProgDVB with /Debug key

Prog, with debug nothing change, the problem is there.

I have also this problem since I started using ProgDVB. Not in all channels, but allways in the same channels.

With my 2 device cards, an "Avermedia volar-x" and "my new Pinnacle Nanostick" the problem is the same.

A comment that perhaps help you, Prog: Curiosly when I change to a channel with this problem and I have the black screen if I open the menu Options and I make clic in "accept" the problem disappears for this channel, not for the other with this problem.

Also if I close the Progdvb and I open again it, if this channel is selected, the problem disappears for this channel, until the next time than I select again changing of channel.

I think is a bug but update after update the problem is not fixed.

You can try change video renderer.

I just try and enhanced video renderer is the the problem continue with those channels (they are free, normal channels as the others).

Anyway selecting enhanced video renderer the image quality is too bad, very dark, compared with wmr-7.

With wmr-9 and wmr-7 also continue, I think is not a problem of the rendering becuase in my case the problem of the black screen is only in some channels, not in all the channels.

Excuse my english.

I put to you the dates of one of the channels with this problem for if can be useful for you:


frecuency: 834000
symbol rate: 8000

sid: 100
tid: 10
nid: 8916

pmt: 100
pvr: 101
video: 101
teletext: 0
ecm: 0

None idea to solve that?

Try install last ProgDVB to new dierectory and scan again.

ps: not copy old settings (ini files)

I installed and uninstalled the full the program and I made a new scann in many ocassions. That does not work.

And still not have messages with /Debug key? I am not have more ideas.

When I open progdvb with the debug mode (C:\...\ProgDVB\ProgDvbNet.exe /debug) I have none message.

Hi. I do usually not reopen old threads but I have the same Problem here.

I already tried all different Renderers and different Codecs.
I use DVB-C (Cable TV).
I can temporarily fix this problem by doing the following steps:

Look up channel Properties,
Starting a Transponder Scan of this transponder using the settings the channel has.

After that all channels from that certain transponder work fine as long as I do not close ProgDVB. I compared the channel properties before and after the rescan of the transponder: No difference. I also increased the Frequency by 10 Hz ==> Then the channel properties are updated after the scan but the problem remains.

I have two partitions and two complete separated Windows XP Installations - I tried on both - the same effect on both

In the Debug Message Window there's also no difference between a visible and an 'invisible' channel. Audio is always working fine.

Any Ideas from anybody?

i have same problem . but now no

the Solution:

go to folder Filters ,, and delet file empgpdmx.ax

Hey. Thanks for this tipp but this is not the real solution because:

I do see some channels where before deleting the ax-File I had a black screen and only audio BUT: Since the .ax-File has been deleted I have some channels where I don neither see and hear anything.

In earlyer ProgDVB-Versions I could delete my GraphFiles by myself. Can I still do with ProgDVB.NET V 6.x?
