i disabled the updates, but it still doesn't work. the internet connection should not be the issue. basically, all runs fine until the GUI shows up. then it basically crashes. "ubuntu login" prompt...

Any thoughts?


1280x720 @ 23.976? - mistersimes - 2011-05-26 17:33

Hi there,

I have a 10 year old panasonic plasma (TH42PWD6). It's old, but it's reliable and it'll take anything I throw at it.

Up until now I've been using XBMC via my AppleTV through the component input, but I've got fed up with the juddering when watching 23.976 content.

I decided to install Crystalbuntu so that I could tweak the modelines in xorg.conf but I quickly discovered that you can't tweak the modelines on the component (TV) out, only through HDMI.

So - as my TV doesn't have an HDMI input, I bought an HDFury2 HDMI to VGA converter. This does its job and I can now set my xorg.conf to output 1920x1080 at 23.976 Hz with the following modeline:

Code:
ModeLine "1920x1080_23" 74.230 1920 2560 2604 2752 1080 1084 1089 1125 +hsync +vsync

In the main, it's really smooth with the odd jump every now and then (not sure why) - 1000x better than 50 or 60hz. However, at such a high resolution and at any frequency, I see really bad dithering - plasma rainbow effect I think it's called, which I don't see at all at 1280x720.

So what I'd really like to do is output 1280x720 at 23.976Hz. I think this would be perfect. I generated a modeline using a generator:

Code:
Modeline "1280x720_23" 29.67 1280 1390 1430 1650 720 725 730 750 +hsync +vsync

But although it's at the right resolution, I get pulsing on the display, I guess because the pixel clock is way too low (29.67). Thing is, I can't figure out how to increase the pixel clock without increasing the resolution.

I've studied all the modeline information, but don't really understand it.
Does anyone else have a 1280x720 @ 24/23.976 hz modeline they could share?

Many thanks,
Si

I re-installed and it is now working again.

Just need to change my xorg.conf file again to allow "component". I know it has been discussed in the forum how to do it, but I didn't succeed. Can someone remind me / point me in the right direction.

Thanks!!!

Crystal HD BCM70012 vs BCM70015 - Ozymandyaz - 2011-06-02 14:54

Hi Everyone -

I posted a few weeks ago that I was going to switch form the BCM70012 to the BCM70015. Well, the results were stunning! The "New" card (BCM70015) works the same, requires no changes in software or config and picture quality looks the same, but performance is MUCH better! The "train wreck" effect (stutter on play or resume from stop or FF/Skipping) is almost completely gone and I am finally able to really "navigate" large videos. There is still some stutter when you start, or resume form pause or do the 30 sec. skip, but its more like half a second where the old card was about 2-5 seconds of stutter.

Anyone considering the Crystal HD upgrade, do yourself a favour and use the BCM70015! Also, NFS shares have worked very well for me.Big Grin

How do I know which I have? I can't remember...


- Hudson_Hawk04 - 2011-06-03 05:28

chances are if it was some time ago (2009) its is most likley the 12 card. The 15 card was released at some point in 2010.

Just updated, got a little worried at first. After the update scripts completed, I was greeted with a black screen and my TV reporting an unusable signal. Another reboot via SSH seems to have fixed things.

I'm having some trouble upgrading my ATV from pin's image (installed on the internal HDD) to Sam's auto-updating image. I used the GUI tool to create the USB stick, but when I reboot my ATV with the USB inserted, the device boots to the HDD, not the USB so nothing is changed/installed. How can I force the ATV to boot from the USB stick on restart?


- Hudson_Hawk04 - 2011-06-04 02:22

it is possible that the atv does not like the thumb drive you are using....
