hello everyone
before i tell you my problem let me first list the specs we use for entertainment, ie. games and tv. right, an intel duo 2.1 ghz, 3 gig ddr ii (was quite cheapish so i guess it's 266 mhz or some such), a pci-e nvidia geforce 8600 gt, and the pci leadtek tv2000 xp global tv tuner which i have wired up to the dstv via composite (those red, white, and yellow jacks), on vista 64.

the images do indeed look pretty clear but when there's a lot of motion for example rugby,frame skipping becomes apparent.
is the solution as simple as upgrading to an external video capture device, or am i overlooking something?
 
The specs sound fine to me - what resolution are you capturing at and are you using the capture software that came with the tuner? Are you using the normal MPEG2 capture or the Hardware MPEG2 capture setting? If using the normal MPEG2 capture, your system will struggle a bit - try using the built-in hardware capture setting - should work fine as it uses the onboard MPEG2 encoder to capture/encode the video.

I had my TV2000XP running on a 2.2 Athlon socket 939, 2GB DDR400 Ram, and onboard graphics card and it worked fine - I was running XP, not Vista - I think Vista sucks up quite a bit of system resources, so maybe try the TV2000XP in an XP system.

Click to expand...

i don't know where to change or see if the settings are in hard/software mode. in winfast pvr2000 there's a bunch of codecs, capture resolution, and the audio codec dropdown boxes. resolutions range between 352x288 and 768x576... i tried all combinations, but to no avail.

prolly my imagination but things look better in 'nero vision', least it has a 'use native settings' checkbox.
anyhow, thanks fo the advice. not the end of the world; i'd just like it to be the same quality as a normal tv :)
 
The version I currently have installed is WinFast PVR v3.0.9.96 (Philips MK3 Series).

If you go into the Settings button, you should see a drop-down box titled Capture Format Profile, or similar - click on the drop-box arrow and there should be a list of all the different profiles available - there should be the usual MPEG-1 and MPEG-2 profiles called Normal, Good and Optimal, then there should also be the ones called MPEG-2 (Hardware) and DVD (Hardware).

If you don't see these "hardware" profiles, then you don't have the hardware-enabled encoder card, only the software version - this will sap your CPU. RAM and other resources...

If you do see the "hardware" profiles, then you should be able to select on and choose "Capture Profile Setting" to change the values - you should select a capture resolution of 720x576 (PAL standard), bitrate mode can be set to "constant bitrate", make the video quality 1000 (or the highest setting), and the target data rate either 4000, 5000, 6000 or 7000 Kbps - if capturing DSTV or VHS tapes, then I use 6000 as a standard. If I capture video camera DV tapes, I use 7000 or 8000 setting.

Select the audio according to your system setup - you may have to play around a bit with this depending on your sound card - hardware encoding usually streams and captures directly, so the setting doesn't really matter, just the source.

Once set up, save that profile you just created and then try and capture - shut down any programs you're not using, and close any others that autostart in you task manager.

If you right-click on your display stream window, you should be able to select the video quality output to the screen - set this to normal quality as this can affect the capture performance on slower systems. Also turn off picture-in-picture, and reduce the preview window size to it's smallest - will help when capturing.

Let me know what happens...
You should be good to go... :)
 
As I suspected the global is a software encoder card. See here.

I have a TV2000XP Expert and I always found it to suffer in performance when running it through XP. I would have thought with a multi-core PC it would perform fairly well. This is based on the fact that on Linux the same card works very well, so my assumption is that the newer windows with newer hardware would eliminate the speed issues.

That being said, my XP machine is a P4 2.667GHz with 1GB RAM. And as long as the Winfast TV Center is all that is running, the output is fine. Is your problem in live TV or recordings?
