Seems odd to me that the CPU utilization would be high due to a USB stick issue? I can try another one and see if that makes a difference but I would expect issues booting if there was an issue with the USB drive - my issue seems to be what the ATV box is doing once the OS is loaded. I'll find another drive and try tomorrow...thanks for the reply.

Maybe not specifically noted - but implied. My understanding is that the Crystal HD card "enable" option only shows up if the hardware is detected - that option does show up and was enabled. Same as when I was running the ATV on the hacked ATV OS. Once I installed the card and downloaded/installed the drivers - that option showed up and HD video performance improved dramatically.
But it's far worse NOW running Crystal Buntu - than it was on the plain old ATV pre-Crystal HD card. That alone makes no sense. Never had CPU utilization at 100% or choppy playback of all video before.

Yeah, I think I'll pickup a new (larger) USB drive and try it all over...can't hurt.
I'm actually hoping to use the PVR features - one of the pluses in this version - just have to find time to read up on how to set that all up. I have an HDHomeRun tuner on my home network and it works great with XBMC going to "simple" route - but I'm using WMC on the main Living Room PC to record/pause live TV etc - and would prefer to do it all in XBMC if possible.
Don't think the PVR aspects would cause issues - or would they? Others are running it succesfully...hard to believe the hardware or flash drive could be an issue. I recall not being able to create the inital USB flash drive when I hacked XBMC into the ATV OS - but that was an overall failure up front - the USB drive just wouldn't work when creating - this CrystalBuntu bootable drive was a cinch to create. If it doesn't perform better this time - I'll try downgrading also.
Yes, running it off the USB drive to test. Can't afford to have the ATV out of service...I'd have a a lot of unhappy people here.
Thanks.

PVR on an ATV ?? is this by using a USB TV tuner ?
if so which ones work on crystalbuntu ? (specifically, is there one that works with a satellite TV box ?)

It's the version of XBMC that gets you PVR - not the hardware. I haven't implemented it yet - but you have to have a TV Tuner somewhere on your home network - "serving" up the TV streams (backend) and the appropriate add-on(s) installed in XBMC to pull it in (frontend). I have an HDHomeRun for my tuner - serves up TV to any PC on the home network- works with XBMC (and yes on my ATV) right out of the box - very simple to setup live TV on XBMC (just live streaming - not the PVR functionality that is). Very cool gadget.
You'll have to do some reading...I'm in the early stages myself.

Ahh ok, sounds cool - not quite what I'd want to do here myself as it wouldnt really suit my setup. But nonetheless worth bearing in mind for possible future setups.

I replaced my LCD TV in the rec room with a 1080p projector - so needed a way to have Live TV via the PJ. The HDHomeRun works like a charm - was up & running in minutes and after editing the .strm files (eliminated one tuner) - we can change channels pretty quickly. Only issue is - the TV works great on the old "hacked" ATV OS setup - but fails miserably with the CrystalBuntu USB boot...hence why I started this thread.
Upstairs I'm still using WMC as my PVR with the HDHomeRun - have it setup so you can go directly to it from a Menu Item in XBMC and when you quit WMC - you're back where you left XBMC. All very wife & kid/remote friendly.
I'm on the waiitng list for a Raspberry Pi also - it sounds quite promising and perhaps could replace my old ATV.

CPU is running at 100% pretty much all the time - can't play back anything 1080p, 720p coughs and stutters from time to time, menus lag and movies take quite a while to start. None of these issues when running on the ATV OS. The CrystalHD option is enabled in the Video settings but sure seems like the CPU is doing all the heavy lifting. How do I determine if the CrystalHD card is working? I'm going to reboot - not sure what that does since I'm running off the USB drive (for now).
Very hesitant to do the full install as I can't afford to have the ATV out of service...
Here's the XBMC.log file (after a second boot - and in two pieces)
Part 1: XBMC.log part 1
Part 2: XBMC.log part 2
let me know what else to post...
Thanks for any assistance.
Try modifying your
advancedsettings.xml (wiki) file so that it says this instead:
Code:
<advancedsettings>
<useddsfanart>true</useddsfanart>
<gui>
<algorithmdirtyregions>1</algorithmdirtyregions>
<nofliptimeout>1000</nofliptimeout>
</gui>
</advancedsettings>
The nofliptimeout part should specifically help with the CPU issue.

I'm accessing the ATV via WinSCP copied the advancedsettings.xml over to my local PC, added the nofliptimeout - but I'm getting an access denied error message when I try to copy it back? Actually, looked at the properties and only the "owner" has W access...same for all files it looks like. I know I used to be able to access/edit files on my ATV via WinSCP - so how do I gain Write access to make this change?

IIRC, you need to type
./configure
When you first SSH in. Then enable the Root account.
Then SSH in using user:root password:atv
That should give you access.

Not sure what the command to change back should be, I don't have access to my XBMC box over the internet, but 755 sounds right. Yeah, sorry about the mixup, should be userdata, not usersettings. I'm going off of memory. Usually when I print out full paths, I have an XBMC box handy that I can SSH into to verify things.
