Most certainly.

I really don't know what is the cause of what you are describing but there are a lot of Revo/ION users around here far more knowledgeable with Linux than I am!

You TV does not sound like it could be the cause as it sounds very similar to mine (50" LG Plasma - 50" Sammy LED) and both Revo's work on both.

Also a family member has a single core Revo which I set up and it handled the Killer Sample fine.

I wish I could be more help . . .

I also encountered this intermittent stutter with the same scenario, XBMC Live (xbmcfreak) Ion system, ripped Blu-ray of Avatar.

Never found out the root cause of it, even with the smooth video fix that is posted in this forum elsewhere.

The strange thing was
* An x264 encode @ CQ18 I made of the movie plays fine as do other Blu-ray's.
* The Blu-ray Avatar run through MakeMKV plays fine on a Realtek 1073DD chipset player.
* Thinking it was a problem with MakeMKV I manually ripped the Blu-ray to an MKV container using AnyDVD-HD, Blu-ray Stream Extractor and MKVmerge and it still stuttered.

Never figured it out and the quality is excellent on the x264 encode so I stuck with that.

Edit: Missed that >>X<<, ignore me then nothing to do with your problem MrCarbo.

Its not an avatar issue he's already said killer sample also plays badly

I assume "shared memory" set to 512?

with the standard (old?) Revo and asrock ion 330 the 911Live repack plays killa sample ok with no tinkering provided bios set up correctly and not playing blue r rip over the net.

If this one does not I can only assume it needs a diff driver.

Yeah, don't think it is the TV.... I've hooked my main PC up to the TV and booted off the Live CD and it works fine... and that's not even using VDPAU or any hardware acceleration - it's an ATI card. So it's definitely something with my Revo - either environmental or something faulty.

Could GPU be faulty...? Are there any Linux based GPU benchmark programs I could use to compare with other Revos?

Something else I've noticed; might be of use... the vq statistic fluctuates wildly when it's stuttering. Playing other media (whether it's xvid or h264) and the vq stays at 99%. Basically any media where the MB/s is around 25-30+ and the vq stat goes nuts and the thing stutters.

Yep, shared memory set to 512.

I've tried the Avatar and Killa sample over LAN and also copied it to the Revo's HDD - same result.

I still wait for a confirmation about which codec is shown when pressing "o" or did I miss that?

Sorry.. it is showing ff-h264_vdpau:

Hannes The Hun · 2010-08-08, 20:49

well then, everything looks fine, XBMC is using VDPAU but it's still stuttering... I'm out of ideas at the moment.

**Vankwish** · (This post was last modified: 2010-08-08, 21:59 by Vankwish.)

Perhaps someone could point you to an standard ubuntu live distro with the correct Nvidia drivers for VDPAU, you could test the file/files in Gnome Mplayer or SMPlayer or the like?

That way you could eliminate XBMC/XBMCLive as the cause, it may be a problem with the Revo (the shimmering artifacts sound like a similar problem i had with my 360 overheating way back when . . .)

Just thinking outloud?

MrCarbo · 2010-08-08, 21:55

Are all other revo users using x86 version of Linux... and what dist are they using? Is everyone using 9.10,9.11 or 10.04?

Hannes The Hun · 2010-08-08, 22:19

have you already tried XBMCfreaks live distro? the revo is probably the most-used and best supported atom&ION system out there, so if your revo keeps having these symptoms it really might be faulty hardware

I downloaded the latest one published on the xbmcfreaks website last night and booted it up off a USB stick. Same symptoms. I've got a feeling there's something faulty, but how heck do I prove it?

You could try sync display to audio clock, in your video settings,

tried that.

I think if you're supposed to be able to boot off the standard Live CD from xbmc.org and play the killa sample without any tweaking on an r3610 then there's something wrong with mine.

problem is... how do I prove there's a fault in order to return it? what benchmarking programs are there that I could run on it and then compare to other r3610 owners?
