Toshiba 22BL702 (B) USB Video Issues

Hello, I recently bought a bought 22BL702 (B) and have been trying to play an .avi movie via the USB, however it says "invalid or unsupported file".I checked the manual online and it says that .avi is supported. Any ideas on how to get it working?
Thanks.

That appears to be a European model, and this is the forum for Toshiba USA. You'll want to contact Toshiba Europe.

  • Ibook dual usb video issue

    hi, i have a dual usb 600mhz ibook g3, the video is screwy you can still make out items on screen, this happens only when booted into the operating system, during bootup the apple logo and grey screen are fine and during target disk mode the firewire logo moves around all perfectly fine, so cant be a hardware issue? ive played with the system prefs and nothing, anyone got any ideas, thanks in advance

    You could try booting into Safe Mode. This will take quite awhile longer than a normal startup because it does a file check and repair of the hard disk.
    You will see your normal desktop. Once completely started up in Safe Mode, restart normally, and go to Applications > Utilities > Disk Utility.
    Select the named boot volume in the left sidebar ("Macintosh HD" unless you've renamed it). Repair permissions on it.
    See if a little hard drive maintenance helps things out.
    If that doesn't help, can you set up a new user and log out and log back in as the new user in order to see whether it may be a preference problem with your user account?
    Do you have the Mac OS X 10.4 Install disc and is it readable by the iBook?

  • Kernel Panic on iMac with Pixelated Video Issues

    One of our work iMacs has been having weird pixelate video issues recently. Sometimes previews of program windows will freeze on screen... and as you move the window around the screen "erases" this preview from the LCD... It is a 2006 24" White iMac 6,1. Now we get some Kernel Panics with the following error message. Please help me decipher it. Thanks!

    Re: Kernel Panic on iMac Intel Core 2 Duo with Lion 10.7.1, 4gb RAM
    27-sep-2011 11:53 (in response to jose guzman) Launch the Apple Hardware Test program, run the extended tests at least twice, and then download and run Rember. All indications are that you have bad or flaky RAM.

  • USB video adapter

    I have a MBpro running the latest OSx 10.8.2. I am wondering any anyone can recommend a stable USB video Adapter. I have recently tried using display link and other such devices however when Mac OS updates the drivers seem to lag on there compatibility and never the less my system crashes. I have recently switched to a matrox dualhead2go ME which works great however when viewing apps at full screen mode it falls to recognize that I am using 2 screen and see my Mac as one giant screen. I am trying to see if anyone out there has found and been able to use a USB graphics card with success and no buggy issues on Mac 10.8.2. my setup is this.
    MacBook Pro i7
    to monitors. one connected to display port and the other I am hoping to connect a USB video adapter. Thanks in advance for your help.

    As stated in a similar thread:
    "This seems to not be possible with OS X's Full Screen mode. I know that since this feature (Full Screen apps) debuted with Lion, this has been a major complaint on the web. You can give your feedback to Apple at http://www.apple.com/feedback/."
    In summary, even with multiple screens, only one full screen app can be utilized as once. I also recommend giving feedback to Apple.

  • USB video capture not working

    I'm having trouble with Skype recognizing USB video capture devices.  I've been doing this for years and now can't seem to get it to work.  I only do this every few months, so I might have missed a post.  I have tried 4 different computers with 4 different USB capture devices, it would seem it;'s a Skype issue.  Anyone else have some ideas?  Will Skype repair the issue?
    Thanks for your toughts!

    This works for me. I have to do it every once in awhile after powering up my PC.
    It may or may not work for you.
    Open Windows Device Manager and for each Universal Serial Bus (USB) Host Controller right-click on it and then left-click on Properties. Ensure that the Device Status TextBox shows "This device is working properly." If not, Disable and Enable that USB Host Controller.

  • MSI Gaming 5 USB ports issue

    Hello everyone,
    I apologize if I posted this in the wrong section, so as the title says it, sorta of a huge USB ports issue just happened after installing the motherboard / windows / all drivers, even restarted a few times
    then tested the processor and video card.
    Everything ok to that point, I left the pc opened for 3 hours, shut it down, the next day..I couldn't type the windows password.
    Alright restart, that maybe one of those kinks that goes away on it's own I guess..Switched each device in different ports..nothing, tried only one device..still nothing.
    Tried only usb2.0 ports then 3.0 port > a a little panic kicked in :D
    So, in my bios I was seeing 2 keyboards 2 mice..ok...got a bios update from msi site..latest one..flash ..reboot..still nothing.
    Strange part was..they were working just fine in bios and everything prior to windows loading, even after that mouse was showing power ( led was ok )but no functionality.
    Safe mode didn't help..the miracle of last known good config saved the day.
    BUT after choosing the option..ok it started working....randomly..I was typing the windows pass...and right in the middle ...it stopped again..mouse was working...tried again..stopped at 75% of the password.
    Tried again...it worked > Reinstalled every driver.. seems stable for now, though being day 2 of this whole deal.
    So if anyone honors me with enough time to read the story and maybe relate I would glady appreciate it.
    Guys if anyone had any usb related incidents with any of the Z97Gaming boards please share
    If I missed anything, please ask.
    Thank you

    Hello everyone,
    Sorry for the delay in all of this and thank you for the input.
    Specs are below, and this is something currently in the process of being upgraded.
    I7 4790k / MSI Gaming 5 / Sirtec 500W / 8 gb ram  Corsair Vengeance / AMD sapphire 7970 GHZ / one single HDD 1 GB
    The Windows installation went fine on 2 other colleagues from work.
    For the moment stable, I removed and reinstalled all USB related drivers.
    It was a weird one though..

  • Toshiba a135-s2246​, USB ports not working

    I just got this laptop yesterday from ebay under the impression it had no issues.  It booted right up to windows vista ultimate and seemed to work great.  Hours later when i actually had time to use it,  the touchpad and keyboard would randomly stop working as if the computer locked up.
    The computer did not lock up, as it would continue on whatever process i put towards (opening apps or whatever)  the power button would work too.  whenever it went to sleep and woke back up the keyboard and touch pad would start to work again.   Whenever you plug anything into the usb ports windows says its not recognized, but lights would come on for the device as if it had power.
    I figured it was just a windows issue.  I did all windows updates, driver updates, reflashed the bios through each version,  disabled/enabled legacy usb,  boot into ubuntu (usb didnt work there either) fresh install of windows vista (usb still doesnt work)  
    I've already did some searching for this as you can tell, im more curious how many other people are having USB port issues.  Frankly, ive never heard of such a thing, ive been working in an IT department since 99 and never seen a laptop with non functional usb ports.

    If your USB doesn't work in Ubuntu either then it's a hardware issue.  The previous owner probably overloaded the USB ports or got them wet.  Either way it will require either a trip to the repair shop or an Express/PCMCIA USB card (depends on which slot your system has).
    If you don't post your COMPLETE model number it's very difficult to assist you. Please try to post in complete sentences with punctuation, capitals, and correct spelling. Toshiba does NOT provide any direct support in these forums. All support is User to User in their spare time.

  • USB videos are not supported by the head rest monitor?

    HI,
    I purchase an XAV712bt HU in India. The video out from the DVD/CD is displayed in both the screens (HU&Head rest moniter). But the video files in the USB is displayed only in HU and not in the head rest moniter.
    Could you please any one help me sort this issue and get USB video output in Headrest moniter.
    thanks,

    Maybe in 2011 when Intel starts using it? There's a website for this here:

  • IPhone corrupts USB video card when it connects

    I just started connecting my brand-spankin new iPhone to my Dell PC and when I do it corrupts the already-installed USB video card.
    I am running a StarTech USB video card to drive a second monitor and I have had it about 9 months and it has worked exceptionally well - until I connect the iPhone via USB cable.
    It hangs the second video output and after rebooting I find myself in an endless loop of "reboot because add new hardware has completed installing new devices".
    This continues even after I remove the phone from the computer. I need to sync with iTunes, so if anyone has an idea on why this is blowing out my vid card I'd appreciated it.
    The system gets so messed up the only thing that I have found to resolves the issue is to roll back to a previous restore point.
    Thank you.

    Given that your post on this conflict is the only one I've been able to find, I'm led to think it is a computer issue, not an iPhone issue. Not a defender of Apple, but I have a Dell desktop and it has its moments of weirdness -- far more of them than my two iPhones put together.
    Originally you said
    "I just started connecting my brand-spankin new iPhone to my Dell PC and when I do it corrupts the already-installed USB video card."
    If you had been using the iPhone for a year and then connected the usb video card, would you then have said the video card has an issue? Perhaps so, but I suspect it may be neither the phone nor the card but something about the computer.
    If you have another computer, try the 3GS and video card with that and see if you get the same result.

  • K9A Platium Video Issues

    Hello again,
    This motherboard and my Radeon x1950 Uber Edition video cards have never gotten along. When I first got the board I could nto install 4gb of ram under XP64. So at the advice of MSI Support I upgraded to the then beta version of the 1.6 BIOS and the mem worked fine, btu it seems this BIOS has caused me other issues.
    No matter what game I throw at this system, it chokes whenever it comes under a heavy load. From Guild Wars to Quake 3, I get teh same results, even with the graphics setting turned way down. I have read here that other peopel have been having this issue with the 1.6 BIOS installed and was wondering...
    Would it be a good idea for me to go back to the 1.3 version of the BIOS and remove two of the memory sticks just so I can at least play my games without the thing dying every few mins.
    I had these video cards and memory in an Intel 975XBX2 and had no such video issues.
    I have the latest ATI dirvers installed for the motherboard and for the video cards (Catalyst 7.7) I use this system only for gaming, so I can not say how it performs otherwise. My specs are in my sig. I have plenty of power for the cards. Other than that I am not really sure what to do.
    So the real question is do I dump 2gb of ram and backpedal to the 1.3 BIOS to see if that fixes thsi prolem?
    Thanks!

    Quote from: lipp7469 on 09-August-07, 05:15:57
    I think I am going to try to go back to the older BIOS with 2gb only, but wasn't there some issues with the 1.5 BIOS? I can always try that first then go further back. That USB bios tool you guys have is one of the easiest BIOS utils I have used outside that windows based one that Intel uses.
    Thanks for the advice, I went back to 1.5 and it is already 110% better. The games fly even when I push the video settings to the max.
    I'm with you, hopefully MSI will fix both with the next BIOS release. (And of course not make any more problems) 
    nice

  • Jabber for iPad video issue

    How can I troubleshoot video issues?
    I setup the iPad device (G711) and then placed a call to a Jabber for Windows (G729) phone. Audio worked fine but no video. I changed the Jabber for Windows to G711 and video started working?
    Is Jabber for iPad going to support G729 and if so when?

    Hi Tony, Ben and others,
    I'm not sure it was the same problem, but a little while ago I have problems too with RADIUS not working on Lion,
    and by searching for solutions I found out that it's necessarily to edit /etc/raddb/clients.conf
    My problem here it didn't work was with the shared secret.
    So I edited /etc/raddb/clients.conf and put at the end of the file :
    client  10.0.0.0/24 {
            secret          =  shared-secret-type-what-you-want-here
            shortname       = private-network
    BEFORE I started RADIUS and added AE's to it
    I hope it solves your problem too …
    GreetingZz John
    PS For some strange reason I had to change the
          'Wireless Security" from WPA2 Personal ---> WPA2 Enterprice on each AE manualy
         But maybe that's just a little bug in when opening the AE in Airport Utility 6.1 cause is WAS
         working before I looked into the AE's
    PPS iPV6 not changed here

  • Usb video adapter not working in windows 8.1 on Hp Envy23

    Since upgrading to windows 8.1 on my Envy 23 all in one, the usb video adapter stopped working.  I cannot get my 2nd monitor to work.  Anyone have a solution to this?

  • Audio and Video issue with Windows 8.1 upgrade on Ideapad n585

    I upgraded my Ideapad N585 to Windows 8.1 the other day, took forever, but it made it through.  Unfortunately, I now get boot erors for the Dolby software, and the AMD Vision/Catalysyt Control Center.  Neither of these programs are able to start, from startup or even manually.  They just won't run.  Sound seems to come out fine still, but I do have video issues. 
    First off, my computer doesn't seem to recognize a HDtv as a monitor through the HDMI port.  I still get an image, but it's set to current screen resolution instead of 1080i.  I tried using the detect button to force it to look for a second monitor (my TV), but it showed nothing connected, though at the time I was using two screens.  Now my monitor's screen resolution seems to be a little higher than my TV's, but it doesn't fit the screen properly, and will sometimes put a black border around the desktop, not using the full screen.  I have also noticed, that when plugged into the tv, if a background program like a screen saver starts (and I am one of the few people who still use them, I like BOINC, sue me), it will reset the screen resolution to what it requires.  When the program exits, the screen resolution stays, and that becomes the new max screen resolution until I restart the computer.  So far, it only does this through the tv, if I run the laptop monitor alone, it doesn't happen.
    I did try updating the software with what's available through the support site, but nothing happened.  I even went as far as to use the Windows 9x~XP standbys of completely uninstalling, manually removing everything from the system registry I could find relating to these two programs, and then finally reinstalling the software.  Giving the audio and video a complete clean slate to work from, and got no positive results.  I restart the computer, Dolby and Catalyst won't boot, and blind to HDtv.  Problems as described above still apply.
    Anybody else have this issue?  Anybody got a fix?

    have you found a solution to this?
    My computer updated to 8.1 without my wanting it to, I have the same problems as you. I installed the video driver because the brightness was locked on what I had it. (the bar would move but did not change)
    I searched for brightness and n585 and I was able to find a driver, now brightness works but HDMI still does not. When I plug in the TV both screens go black with all 4 options in the "project" screen.
    *edit*
    this worked for me i stumbled across this
    I unplugged the power cable with the hdmi cable plugged in. Hit (windows key+p) scrolled to duplicate and it worked.I plugged in the power cord back in and it still worked.
