Do you have a disecq switch connected as part of your satellite setup? 
I seem to remeber reading that HVR-3000 doesn't work with them (yet)?

I must admit, I feel much the same about my HVR-3000.  The DVB-S 
reciever seems to need a *really* good signal - better than my cheapo 
FTA set top box.

When I bought it, I thought I'd be able to record DVB-S, DVB-T and 
analog simultaneously - I tried once, DVB-S + analog and only one would 
work at once.  The analog tuner seems pretty poor - both quality wise 
and the fact that it has problems detecting/loading the tuner module (so 
poor that I don't use it).

Having said that I've have DVB-S working well enough since the start of 
this year.

The linux driver support isn't great.  Steven Toth seems to have done a 
good job (they work for me(tm)), but they've somehow gotten stuck in in 
DVB and don't seem to be getting any nearer to the mainstream kernel 
tree which is a shame.

Sorry, I don't really have any more suggestions for what you can try...

Robert.
