It has 2 scart sockets and I have one connected to TV and the other to a DVD
player. Everything seems to work OK, wether I choose one or the other setup
scart option.

Of course I have mailed Topfield about this, but I suppose they don't know
themselves as I don't get any reply.

My sat receiver has no s-video socket.

So far I have recorded succesfully with the RGB setting. Haven't tried
recording using the other settings yet.

You're absolutely right. I was only verifying wether I use the best settings
and connections using the gear I have. And I'm allready getting better
quality than the average TV screen can reproduce.

That would be ideal. I'll keep it in mind for the future. At this time I
record in AVI format, so I can do lossless editing (cutting out commercials
etc.) and as the very last step converting to DVD compliant MPG for making
DVD's.
With this DVB-S card you mention, does it write the recording in compressed
MPG format to hard drive? That would not be ideal for editing and
re-rendering.
