*Stop press*

I have detected a little artifact in the sound from the Argos stuff this
morning - not audible in normal use (even right up to the speaker), but
when
playing back *recordings* and trying to record them with a little mic
there's a little 'whumpa whumpa whumpa' going on at about once every
second
(or so) at quite a low level....???

It's here at about 600K:

Exactly once per second by the look of it. Does it have a clock, or
could this correspond to the update rate of the display?



???

No idea! But it doesn't have a clock. I'm sure I've heard this noise on some
PVR playback and then when I tried to record 'open mic', otherwise I hadn't
noticed it!!

Here's another one - I have a Hauppage WinTV card in this machine and have
just tried to install the crappy software (WinTV2000!!??) that came with it.
I might have aerial issues (whenever not?) but is there any better software
available to use with this card before I start crawling about in the loft? I
was using ShowShifter on the old machine but seems to have gone tits up!!
