I can't export video

If you want to transfer data contacts from iPhone to pc, you can try iOS Assistant. With its help, you can easily access data contacts on iPhone and export them to pc directly via usb cable. https://www.coolmuster.com/idevices/transfer-contacts-from-iphone-to-computer-pc.html

That's not difficult. You can first convert PowerPoint to video format and save it in an USB drive/SD card. Simply save PPT file as WMV from the option. Keep in mind that the exported WMV file does not have audio. So if you want to remain sound, you may need a more professional PPT to video converter on your computer.

you might have lower video card specs, or the version is not compatible with os

Hi,
It sound like you have a defect codec installed. Try updating (uninstall / reinstall) your codecs.
or disable the codec befor trying to export.

Did you want to download this video? If you did, you can use some program to help you to extract youtube video you like, and then export them to your TV. I often do it, so that I can watch online TV shows on my TV. 

The Tuner signal board have intermittent problems.Tries websites like Shopjimmy.com,Ebay.com to by a refurbish Tuner signal board for the replacement.

Probably DVDSP can't read the format you exported from FinalCut. Either try to export another format from FinalCut or use a converter like Compressor (You might have when you use FinalCut) to convert the exported file.
I can personally recommend HandBrake which is a graphical frontend to FFMPEG to convert/transcode video formats.

Your JVC should of come with appropriate CD for exporting and editin videos. If it did not you can use Nero, all you have to do is go into your Nero settings on yoour computer and inport the footage from your camera. If this doesnd work try cliking on my computer and click on the new hardware that apppears, you can then export from here to Nero. I hope this helps

Use a sd card in the flix, for the most part, camera's, phones, if they have a sd card,or memory card, the pc might see the card and load it as a drive, as you said you looked under my computer.

You should also get a cheap sd card reader, a few bucks,$5-6,
this way, if your pc does not see the card, you can put the card into the reader and plug it into the usb port, and import/export all day long. Not sure if this flix can format the card,read your manual,
but always format the card once(new card) with the flix, and never format the card with windows. Hope this helps.

Capture it as a standard video clip (with audio), then export the audio track out of Final Cut. If you export as 48 KHz, 16-bit stereo, then there should be no loss in quality as the output is the same as the captured input.
