SOURCE: resetting the progressive scan mode on an LG lh-d2645 home theatre system

the above is correct but you need to have the dvd player on with no disc in so "no disk" is shown on the front display. then hold down the stop button for 5 secs to reset the display mode back.

The Manual for your LG DVD Home Ent unit says: Some DVD+/-RW, DVD+/-R or CDRW, CD-R cannot be played on this unit due to the recording quality or physical condition of the disc, or the characteristics of the recording device and authoring software" So If what you burn on your PC can be played on another stand alone DVD Player Recorder than I would say that the problem is just that, not compatible media. Codecs, Firmware Update, Recording software used and Region Code can play part in problems, just depends on how much you can eliminate yourself.

Check the region and picture settings on the home theatre's dvd player, it could be set to put out a component signal, or it could be set to a PAL region rather than NTSC

How to redirect the sound of my new LG 52" HDTV LCD to my LG home theatre?


There sould be audio outputs on the back of it, and the manual should clearly show how to set up a home theatre with an external sound system and all.

I don't know what kind of sound system you have, but I think it might be best to connect your video source (typically DVD player) to your sound system, as it usually can be done better that way. No need to introduce another link in the chain (your TV) that could degrade sound. Also any external tuner could (should) be connected to your sound system directly.

If you use the internal tuner in your TV to watch TV the audio out is your option. Best way to get this right is to consult the manual. They usually have some diagrams that shows a few options of how to do it.
