Yes it is an IDE DVD drive and an old one (x2) at that. It's a Toshiba 
Equium, so the motherboard is proprietary (& a bit strange -
power goes in on the PCI riser card for instance).

I have noticed that DVD performance (stuttering) changes depending on 
which part of the disc is being accessed. When playing
a DVD the drive light flickers on briefly about once a second. If the 
flicker is quick there is no disturbance, but if the led stays on
longer then both the sound & vision stop until the light goes off again, 
so it would seem that IDE access is the culprit. I could dig
up a faster DVD drive to try (and may well this evening if I get a spare 
moment).

I was (and still am) hoping that a newer kernel with adifferent 
scheduling algorithm (i.e. a  max latency version) might help this old 
PC - it
certainly compiles and runs fine, but (of course) I can't get DVB, or 
vdr to compile with it yet.

On the other hand I have loaded the new 1.0pre-whatever DVB driver and 
that seems OK (actually no different), which means that
the tuner in my DVB-T card comes and goes, while the Nova-T card is just 
fine.

One day I'll get there and can watch TV without the need to have makes 
going on at the same time !
