[linux-dvb] HAMA DVB-T DST and bad signal

["Stefan Schenk" <steffx@pfroen.de>]

Title: Nachricht

Hello List,

 

     i have a DVB-T card from HAMA, which is detectet as a Twinhan DST + clones from bttv. dst recognize the card as "terrestial TV".

I can also tune the card to my local dvb-t channels - so far so good.

The problem i have is, that the signal-strenght is max. arround 30% which is too bad for some channels - i get a very bad picture.

When i test the card under windows whit the same environment i get a perfect picture and full signal.

I was talking to other people at vdr-portal.de which have the same problem with the HAMA-card.

Does anyone have a idea what the reason for our problems could be ??

 

here is my dmesg - maybee it is usefull :
