Hi there,
What capture card are you using to record TV?
I would expect most people these days to be receiving some kind of
digital signal - DVB-T using an aerial, DVB-S using a dish or DVB-C
via cable. Here in the UK, for example, it would be most common to
receive DVB-T "Freeview".
Receiving a digital signal requires no encoding, practically no
processor resources, as the DVB signal is just mpeg, and the card is
simply dumping the stream to hard-disk.
Are you playing back the video across the network?
What processor / RAM configurations do your PCs have?
What hard-drives?
What size are the videos (pixels) and what format (encoding, bitrate)
are they stored in on your hard-drive?
I think you have to demonstrate that the problem is processor-bound.
My immediate thought upon reports of stuttering is to question disk
or network throughput.
Stroller.
