[linux-dvb] Dvb card sensitivity to power supply

[Kartsa]

I have a Hauppauge WinTV Nexus-CA dvb-c card and a WinTV-Nova-C budget 
card. For some reason lately there has been more and more problems with 
the picture. Femon shows that the signal is good (ffff) and snr is not 
so bad either (e0e0 or better). I remember reading somewhere that these 
cards are quite sensitive to how gow good the power supple is. Has 
anyone noticed any similar behaviour? I mean should I by a new power 
supply? Would it be worth it? The power supply is some years old though.

I would apreciate any hints / advise.
