Ever so slight video hiccups driving me crazy

Deinterlacing is used for a progressive display which you don't have. It's not that
are you sure of this i know the final out put has to be interlaced but before that isnt it deinterlaced by the computer then interlaced again and this is where the problem comes from i thought

I wouldn't think so, but I don't know for sure. You might be talking about whether the source is interlaced or progressive. The display system has to treat this data differently, when it upsamples the chroma info.

I'm running PVRX2. It's really random. I _think_ that it only happens in live tv, but I could be wrong. I guess I can do a test record on one of the news stations to check.

You can't change the renderer as I was suggesting since you are using PVRX2. It doesn't run VMR7 or overlay. Try the quartz.dll fix. Don't know if you can burn a DVD or not, but if you burnt a DVD and popped it in your player, and it didn't stutter you would know it is somewhere in your system but not the recording itself.

maybe someone else can clear this up but from everything ive read when a computer plays a interlaced signal it deinterlaces it then reinterlaces it
if it outputs it to a crt tv
plus it makes a diufference in pure video if you change the deinterlace setting so this leads me to beleive at least on mine it make a big difference
but i am open to someone correcting if i am understanding it wrong

[stustunz]

on pvrx2 only vmr custom or vmr exclusive works
so if he wants to use overlay or other vmr he can open the gbpvr.exe instead

I'd try to determine this as a first step.

what video decoder are you using when you get this stutter?
and what decoder settings

this is a tricky one.....do you have agp or pci-express video? and if agp, is it 8x?
i get better performance by actually turning off the smartgart agp fastwrites and direct memory transfers..[in catalyst]

that and that video card isn't quite up to the memory speed requirements..
the 9600 was the minimum for dx9 vmr to run smoothly, and even tho the 9550 is the same gpu chip, the memory is much slower..

the ATi video decoder from avivo is fine, it's auto-adjusting on everything, and does it well...that's not the problem,i bet any codec you use will show it..

it's funny but these cards do fine in MCE even with hi def stuff, but MS uses stream buffering and read-ahead caching and all sorts of other cheating to make it smooth...but even they require a 8x agp with 10mbit memory bandwidth and 64 meg mem to work properly..

looked fantastic when i setup a mac os on same hardware, so can't be hardware..
it's like transferring files on a MS network...no matter how fast your connection, they waste 80% of it for some unknown reason, you can never ever use the full bandwidth...most i've ever gotten was 45-50%

It's an agp at 4x . agp fastwrites are off (I can't enable it either). I couldn't find the direct memory transfers setting.

Smart bet. I am seeing it will all decoders but the ATI version offers the least amount of problems. The decoders I'm using came from the install disc. Are the avivo drivers an updated version or is it the same thing?

I'm not against buying an updated ATI card if that's what my problem is. I'd just hate to upgrade and find the problem still there. Any model suggestions are appreciated. This box is agp only. I'm also, as always, on a limited budget.

try vmr7...works great for me...no jitters and all the vmr smoothness of picture..
none of the cute features of vmr9 custom or overlay, but very watchable..
it's that or overlay for a perfect picture on lower end systems...
for pvrx2 you'll probably need a better card...

[pBS]

oh and try vmr9 full screen exclusive mode...it works wonders and will probably fix that hiccup, but it has other odd side effects...but video looks excellent..

it also works in pvrx2 so that may also be an option for you..
[use "pvrx2.exe -fse" to start it in fse mode]
