    Default MythTV problems with Sat. Anyone else ?

    The last few days I have been having problems with watching recorded programs or live TV of the Sat. I disabled sasc-ng and reconfigured MythTV to use the real card, not the virtual one from sasc-ng. I tuned into Help channel and I still get the same errors. So it is not cam, card or key related.

    Code:

    Anyone else having problems with it or is it all working fine for you ?

    Just an update to anyone interested. I put a 6600GTR PCI-E in just recently. It was fan cooled until the fan feel of it a while ago. So it is now passively cooled. It seems the heat it is generating it knocking the tuners out (2 x dvb-s cards). I took the lid of the PC and after about 10 minutes the BER dropped to 0. Getting a proper passively cooled 7200 in the next few days to replace the 6600.
