OK - I now have a 300W power supply and there is not much change. (Well, now my irman works again and thats a good thing ;) but no change to the dvb behaviour). Now, the errors I am getting could well be due to a mis-aligned dish. It is worth noting that my stand alone receiver is also having problems since I plugged my budget card into its loop-back port. I think that is just a coincidence. I was away when my card arrived and set it up as soon as I could - it could be that my stand alone receiver/dish were in fact not working well since some time when I was away. We did have some storms while I was away. On the fault where without the receiver powered up I get no signal: Could it be that my budget card simply cannot power my LNB? This is a c-band LNB and so perhaps it has a high draw? > Holger > -- Info: To unsubscribe send a mail to [EMAIL PROTECTED] with "unsubscribe linux-dvb" as subject.
