Stuttering after 3.0.11 to 4.0 Upgrade

[DynamoBen]

Moving the cards seems to have helped. I still get the very infrequent stutter. Audio always remains consistant. I now know for sure the issue is encoding and not decoding. I burned a file to DVD that had the stutter and watched it on my DVD player. The stutter isn't as dramatic but it is there.

I wouldn't call this case closed as of yet. I'm currently updating all drivers for the MB. Sharing an IRQ should not cause the stuttering problem.

The bizarre thing to me is that I did not have these problems before moving to 4.0. I was using 3.x with no problems. I haven't changed the hardware configuration or the drivers just uninstalled 3.x and installed 4.x and now stuttering and weird recording problems.

I'm having this issue as well.

I'm still running into the problem. The other day I uninstalled 4.0 and reinstalled 2.8. Problem still existed with both pvr250s.

I have since gone back to 4.0 and I'm now in the process of moving cards around.

Are we all using the 250?
What version of java?
What brand/model video card?

I'm just trying to look for a common thread.

One note-
I only seem to be having this problem with Live TV.

I then downloaded a 30 day trial of the Bronze NVIDIA Decoders ... Installed and selected them in the Sage Video Settings ... Yep, same problem ...

So, I still haven’t conquered it ...

I have an ECS MoBo and have installed all the HW drivers provided. The Device Manager seems to be happy with no yellow ! ...

I am still stumped and looking for suggestions ... Won't do me any good to have a great new Sage 4 interface, Studio customization and new cool / quiet HW when the fundamental PVR recordings tear and stutter all day long.

Thanks, T.

I "may" have solved this problem on my Sage 4 Server ...

After installing the NVIDIA 30 Day Trial, I played the recordings that were stuttering and tearing before and they still had that problem. So I decided to wait and record shows with the new decoder and see if thatworked ... I watched enough of them to believe that the NVIDIA decoders did the trick for me. Even withan ATI card!

LiveTV also works better as well ...

We'll see if this lasts or changes for the worse ...

I think we have a couple of different problems here. I'm not seeing any tearing at all. What I'm experiencing is stuttering/dropped frames during live TV streaming. There is no tearing, and switching decoders or playback methodology (Overlay, VMR9, FSE) makes no difference. I've looked at network activity, and there's neither a huge peak nor a complete drop when it happens. There is a noticeable drop in CPU activity, but this is probably because the decoder is working on fewer frames.

My setup is identical it when I was working with v2.

OK my problem appears to be purely playback now...what happens periodically during play back I will get jreky slow motion playback. I am not recording anything at the time. I am not sure why this happens. I have tried different decoders. Running bare bones software on the box...but I can not come up with a reason...definitely not CPU bound...I am doubting disk.

I seem to have the same problem on a standalone hdtv server. CPU usage is only at 75% and I can view things in VLC just fine.

Specs are P4 2.8 (no ht), 1 GB RAM, nvidia Geforce 6800 128MB, SB Live, and a SiS matx mobo. Nvidia purevideo installed.

This is what I experience as well. Just stuttering at random times in playback. The most noticeable time it happens, is during fast motion, such as panning.

I've only had the problem since V4 as well. I upgraded chipset drivers and video card drivers, and neither helped.

I too was having trouble with stuttering, that is why I have read these posts. I had been running 4.0 and was not having any problems. Then my brother came to visit and left me a bug, I had to wipe and reload all. When I rebuilt the computer I had a stutter as is described here. I was very suprised that when I got up this morning I was informed that windows had updated my computer and rebooted it. The best part of this story is that my stutter has gone away.

Well I think I figured out my stuttering problems.

It appears that stuttering occurs on my f: drive. I did some looking and found a S.M.A.R.T. Monitoring tool at http://drivehealth.com/.

Ifound out that 2 of my hard drives were over heating - my boot drive actually and also that it was predicting that my 300GB Seagate F: is going to die some time in the next few weeks. Basically it is estimating based on all the read failures and also the high number of other I/O Failures. I have also noticed that starting / deleting / stopping recordings on those drives have become slow.

Might be worth a look....I am probably an exception in terms of this type of error....I guess it is time to buy that RAID 5 Setup....no more missed shows...the wife is starting to get annoyed.

Live TV seems to be the worst, but also when I use the OSD to jump, or FF I really see it. It continues until the OSD dissapears from the screen. This was working perfectly under 2.2. Sigh, I also have upgraded from Win2k to XP Pro at the same time, so I guess I asked for it. I am fairly certain that this has something to do with my video card, I tried using an ATI AIW 7500 and everything was stuttering (blasted .NET junk) so switched back to my nVidia Gforce 2 MX and there is only stutter when I try to FF and skip now. I hope that an older driver is going to fix this for me, as someone else in here mentioned.

Ok I am rather dissappointed with the 660GT / PureVideo Decoders:

I have the lastest NVidia Drivers 81.95 and I downloaded the PureVideo Decoder trial. I tried using the FSE Mode and VMR9 and it could not playback and HD test file smoothly. I checked and it was only using at 40%, so it can't lack of CPU power. Then I tried in overlay and it was nice and smooth and looked great. Then I went watched a regular show and it would not fill my 1280x720 screen in fill mode and looked as if it was centering it as if I had a 16:9 display. In VMr9 Mode it worked ok, but even in FSE mode it was tearing. I uninstalled the purevideo decoders and installed the old Nvidia 2.55 NVDVD and tried again. Even in VMR9 mode playback was smooth and no tearing on standard TV. It still could not do HD sample smoothly, but works perfectly in Overlay again CPU never excedes 40% during playback in VMR9, I just don't understand how playback could be so bad on decoders supposedly optimized for HD playback on a card that it is supposed to be optimized for.

I am not regretting the card purchase since it has 2 DVI ports and HD component, but still rather annoying.

I haven't watched long enough to know if the stuttering is gone in the new setup, but I suspect it is.

Well I have formatted the drive and reinstalled XP, with the updates. The issue is now only with live TV. Sigh. All of the drivers have been updated, and the nVidia was rolled back to the older version as well with no noticed change. I have not reinstalled the NON-CSS Haupp codecs yet, I guess that will be my next step. After that, I am guessing a big %$#@#$% hammer will go well with it. I also reinstalled V2.2 and see the stutter after the format, so I believe that this is now something related to the OS. Probably a setting that I have missed, but having fooled with so many, I may be duping efforts, and not realize that I have done something 5 times already.

Try downloading the version of the driver issued in September. I think some have reported better results with it. If I wasn't so lazy, I'd have done it myself.

Well...I actually RTFM and I found out that they recommend only using single Display mode for Video playback. I finally fixed my office computer so now I am using Single Display mode using DVI at 720P to my HD TV and I can now play HD using VMR9 and FSE smoothly with no tearing.

Last night I did expierence some stuttering during playback in a few spots. I am stiill trying to figure out why.
