Hi Todd !

Thanks again for your input ; sorry for starting a new thread..

To answer your questions and provide some information :

About the tuner :
- The tuner is a Hauppauge WinTV PVR500MCE Dual Tuner. I am using the driver
included in the latest download from hauppauge : MCE_CD_v25.zip.
- I will copy a recorded TV show from one of my colleagues and try this asap.


About the network :
- The card is a 10/100/1000 integrated network card on the motherboard. It
is a Marvell Yukon. I am using the latest driver available directly from
Marvell. I also tried using a Compaq NIC (NC3120), but to no avail. My
network is 100Mb.
- The MCX Network Performance Tuner reports i have sufficient bandwidth to
run the extender. The graph is displays is entirely green (so maximum
bandwidth is available). Monitoring network performance while the extender is
running gives a network load of about 10-15%.
- Recording a TV show in fair quality does not make a difference : It just
gives a jerky playback of a lesser quality recording :-)

I also tuned the PC so no more IRQ's are shared anymore : USB is disabled,
as are all the serial and parallel ports. I moved PCI cards around to trigger
ACPI to assign non-shared irqs.. No difference.. BIOS is latest version,
default configuration.

I cannot stand the fact that i cannot find out what component is causing the
problem. I am very much hoping to find out with your help though, Todd..!

Thanks.
