picture capture clarity

When watching LiveTV GBPVR uses the LiveTV settings. When you press Record I would have assumed it continued using the LiveTV settings unless Sub has changed this.

tipstir,

ATI Radeon X300 SE (128MB PCI Express x16)

i'm set at 32bit, 60hz.

in gbpvr:

NTSC 720x480 / PAL 720x576
Constant
5500 Kb/s
9000 Kb/s
224
48 Khz

any ideas? i'm still a bit fuzzy, and once in a while jittery at full screen.

i see no significant difference. picture is still a bit fuzzy.

You have you recording set to constant, which means all frames are encoded using 5500kb/s. If you change this to variable then it will have an upper limit of 9000kb/s. On the jittery screens was it fast moving action? This requires more bitrate so as you can see on constant it will possibly not get enough, hence the jittery output.

I have a 19" flat panel with dvi cable and I thought my picture would be better too. It's ok but not as clear as I thought even after the sharpness tweak. I don't use it to watch tv too much, just to record but I'd be interested in cleaning it up just a bit. Let us know if the RCA or Monstor cable helps you.

Remember, garbage in garbage out!

That's what I meant by my first post in this thread. I would recommend that you have a good coax going into your tuner first. And, if you used a splitter for the connection, make sure it is a good one.

This is what made the biggest difference for me and I had also tried the sharpness tweak etc...

Before replacing the cable I was not really satisfied with the picture quality. It was 'OK' but not good enough to use all the time. Now, however, I am very happy with it. In fact, I pretty much use gbpvr for all my tv watching now, live or recorded.

I am not running a killer machine either. I have an AMD Athlon XP 1800 with 1GB RAM and an ATI Radeon 9700 Pro and a pvr-150 tuner. This I use with an MVP connected wirelessly (2 linksys wireless G access points) to my TV.

Good luck!
Eric...

i have no gotten a new coax. i am currently using the one provided by my cable company. the line coming in is also split (into 3) again using the material provided by the cable company. i've run dscaler and the picture is very crisp. gbpvr does not compare.

yes, the jumpiness comes when fast action.

Iv been having some simmilar problems, Now my picture is clear when I run it at 640x480 with a high live tv setting ie: 7000 -> 9000 and I'v tried a lot of refresh rates but the problem persists.
The problem is that the out put to TV looks as if frames are beeing dropped causing for a slitly jumpy feedback, and there are sever motion trails durring action almost as if you were seeing the last frame of interlassing with the current frame

I just recently compared this to wintv200 and the frame and motion trailing was non apperant the color and quality were off but that can be fixed

so my theory is that there is a setting in gb-pvr that i need to tweek am i correct please advise

Oh...and I have tried different codexs (windvd 6, NVdvd) all look great but all have a frame dropping and motion trails

Its possible you have a codec installed that has a high system merit, which will cause the system to use it in preference to the one your specified. The mpeg encoder installed with FFDShow has been known to do this. There may also be other decoders out there that do this. Remember, GB-PVR doesnt to do playback itself - it simply hands the task over to these third party decoders, then steps out of the way.

how will a codec pack help me? the 150 should be doing hardware encoding... ?
