Windows 7 LG 42LH3000 Windows 7 driver

[thewoodies]

Hi

I have just purchased an LG 42LH3000 TV to replace my older Philips 32". I have a HTPC running Windows 7 Prof 32bit. The Philips 32" lcd was plugged in HDMI to HDMI and recognised fine in device manager with my setup. I was using Roxio CineplayerBD to play my DVDs and Blu-rays without a hickup.

When I swapped over to the LG TV, DVDs stopped working. Not tested Blu-ray yet as I didn't have one to hand (I use lovefilm). I get an error message in Cineplayer just saying there was an unknown error and to update my hardware. Windows Media Player gives this error: 'Windows Media Player cannot play this DVD because there is a problem with the digital copy protection between your DVD drive, decoder, and video card. Try installing an updated driver for your video card'. I updated to the latest nvidia driver and still get the same problem.

In Device Manager, the LG is seen as 'Generic PnP Monitor' which is where I think the problem might lay. However, in the nVidea control panel, it sees it as an 'LG TV' and it also reports there that the system is HDCP compliant.

So I am at a loss at the moment as to what to do. DVDs play fine in VLC player but I know this uses its own codec. Anyway I want to use Cineplayer and keep it simple for the family. I have emailed LG support to see if there is a driver but I am not expecting anything useful back. There is nothing when I search for 'LG TV driver' in google.

If anyone has any ideas I would be very thankful.

It seems like your issue with playing DVDs on your LG 42LH3000 TV through your HTPC running Windows 7 Professional might be related to the display recognition and compatibility with the software you are using. Here are some steps you can take to troubleshoot and potentially resolve the issue:

Troubleshooting Steps:​

1. Check Software Compatibility:
   • Verify if Roxio CineplayerBD has any known compatibility issues with your LG TV model. You can check their website for any updates or patches that might address such issues.
   []Update Software:
   • Ensure that you have the latest version of Roxio CineplayerBD installed. Updating the software may resolve any compatibility issues with the new display.
   []Check HDCP Compliance:
   • Since your system is reported as HDCP compliant in the NVIDIA Control Panel, the issue may not be related to HDCP. However, it's good to double-check if all devices in the playback chain (DVD drive, decoder, video card) support HDCP.
   []Update Graphics Drivers:
   • Confirm that you have the latest graphics drivers installed for your NVIDIA video card. Sometimes, a fresh driver install can resolve playback issues.
   []Check DVD Region Settings:
   • Make sure that the DVD region settings on your computer and DVD player software match the region of the DVDs you are trying to play.
   []Monitor Recognition:
   • The fact that your TV is recognized as 'Generic PnP Monitor' in Device Manager might indicate a driver-related issue. You can try to manually update the monitor driver to see if it helps.
   []Alternative Playback Software:
   • If the issue persists with Roxio CineplayerBD, consider using alternative software like VLC Player for DVD playback, which you mentioned works fine.
2. Contact Manufacturer Support:
   • It's good that you contacted LG support. They might be able to provide insights or any specific drivers or firmware updates for your TV model that could address the playback issue.

     Additional Notes:​

     • VLC Player uses its own codecs, which is why it can play DVDs without issues, unlike Cineplayer.
     • Ensure that all cables are properly connected and there are no loose connections that might affect playback.
     By following these steps, you should be able to troubleshoot the issue and hopefully resolve the DVD playback problem you are facing with your new LG TV and HTPC setup.
