Early teething problems

[John@TunerUK]

I've just installed sage onto my HTPC, ran the setup, and everything was going well (Well, apart from not being able to setup my leadtek DVT1000T). The Hauppauge nova t 500 setup easily, and the remote works brilliantly. That was however till a recording started. My AMD 4200+ Dual core is now steaming away at 100% on both processors, leaving the PC pretty much unuseable for anything else. I can't even fiddle about with settings, because inputting each digit takes a full 20 seconds.
Any idea where I might have gone wrong with the setup?

System entails

abit AN-M2HD Motherboard
AMD 4200+ Dual Core processor
1Gb DDR2 RAM
Samsung spinpoint SATA II 500gb (50Gb for OS and progs, and the rest partitioned at 64k blocks for storage)
Hauppauge Nova T 500 Twin DVB-T card
Leadtek DVT1000T which crashes sage as soon as I select it as a source (So currently lies dormant)
Antec Fusion Black case

Well, I found the problem in a rather unexpected place. The VFD on the antec case was using all that processing power apparently. As soon as a recording started, the VFD began to use 99% of the processing power on both CPU's. With the VFD turned off and sage recording, CPU is down to 3%-4%.

Who makes the VFD/what software does it run? A new version (3.0.3.1) of the MPlay software from VL Systems (Zalman HD135 VFD) has a bad memory leak (500MB before I shut it down). v2.0.1.4 is fine.

It's the Soundgraph IMON VFD and IR Remote reciever.
I've searched for any updated drivers, but the website is a bit unclear about what driver supports what.
