True, it all depends on special routines, like SSE and such, so one
implementation may be much faster then another. But I think overall the
Athlons are still up to par with the P4, despite the latter having a much

Yes, I'm aware of that. Maybe I overestimated how fast an Athlon is.
You have a good point Re: I/O too, if one harddisk has to write two streams
chances are the head will "thrash". But then again, that happens while just
booting windows so that's no real showstopper ;-)

As I said, I had so much trouble that I suspect either a PCI conflict (which
this BIOS cannot resolve: no settings) or one of the cards is botched.
I think I may try to find a resolution that just enables two-card recording.
But I might also go for a PVR250. A third possibility may(?) be to use a
frontend. I'm not sure what a frontend can and cannot do. But if it can
record too, this may and idea. I doubt it tho, buying another fast system is
definitely more expensive than a PVR250 card, or even two of 'em.
ATM I have worse problems; in an attempt to do the filldatabase manual import
and subsequent inserting and tuning of the channels I somehow managed to get
everything mixed up. I now have a Live TV screen showing Channel "NL 1" but
the programguide in the OSD tells me it is an entirely different station...
I fail to comprehend how all settings like channelnumbers work together. How
do you renumber channels, or is that a no-no since it does exactly this...?
I suppose I have some reading to do (but where?) and I probably also should
fire up some database client to look into mysqls' tables directly.
Thanks for your help!
