Hi there, |
16 |
|
17 |
What capture card are you using to record TV? |
18 |
|
19 |
|
20 |
I would expect most people these days to be receiving some kind of |
21 |
digital signal - DVB-T using an aerial, DVB-S using a dish or DVB-C |
22 |
via cable. Here in the UK, for example, it would be most common to |
23 |
receive DVB-T "Freeview". |
24 |
|
25 |
Receiving a digital signal requires no encoding, practically no |
26 |
processor resources, as the DVB signal is just mpeg, and the card is |
27 |
simply dumping the stream to hard-disk. |
28 |
|
29 |
Are you playing back the video across the network? |
30 |
What processor / RAM configurations do your PCs have? |
31 |
What hard-drives? |
32 |
What size are the videos (pixels) and what format (encoding, bitrate) |
33 |
are they stored in on your hard-drive? |
34 |
|
35 |
I think you have to demonstrate that the problem is processor-bound. |
36 |
My immediate thought upon reports of stuttering is to question disk |
37 |
or network throughput. |

Stroller. |
