Causes for stuttering TV (2 Viewers)

[SweMart]

Another possible reason is overheating, my Twinhan TER-CI PCI card causes stuttering live tv when I gets over approx 45C.

Twinhan card are known to have problems with heat (from what I've read on other forums).

Would somebody make a sticky on this subject;


Causes and solutions to stuttering/choppy TV
Tried all above worth trying... also tried "disabeling index service" and reduce system resources used by other apps. and services, and set up AAM on HDD.
-> still not flawless

What is the (Setup->Televison-->) TV-card priorty good for?

The TV card priority is used if you have more than 1 tv tuner in your PC. Ignore it if you only have one. What Codec are you using for TV? I had serious issues with the Cyberlink codec and eventually went back to the MPV codec bundled with MP. It doesn't support hardware acceleration but it works ... I also found that channel zapping when timeshifting is damn quick for me with MPV.

I have live Tv stuttering problem too. I have Leadtek winfast tv2000xp expert sw tv card and is stutter without timeshift too.

The cpu usage about 60% during live TV and it never goes upper than 80% so I think my CPU is enough for MP.

Somebody said changing audio-renderer (typo) did the trick.

Thought it sounded strange - but did of course try.....

IT WORKED! No more stuttering after "default" a-r (not gonna try to write it again)!

My rams run in dual mode.

... I think the wireless lan signals were interfering with the TV reception...

You rock ! So simple. I had determined that when I right-click disable my wireless connection, tv worked fine. So i was assuming it was a PCI/IRQ confilct or pci bandwidth. But I switched antenae with my other box, that has a short lead instead of direct "stick", and hey presto ! Great HiDef TV.

I've also experienced that increasing the PCI Latency Timer in the bios from 32 to 64 can solve a number of problems that can occur with Hauppauge cards, like stuttering, signal/frame drop, noise, or no signal at all..

It worked with my Hauppauge PVR500 card, but could also be the case for other cards?

I haven't seen this mentioned anywhere, but if I have the grab EPG from DVB option enabled with any of my Dvico cards the TV pauses regularly. Disabled this and it all works fine ? Also, my original stutter problem when I first started using MP was that I only had 256MB of memory, 512MB and all stutter went away.
