    Many of you helped me do my research in stopping for a new flat screen digital TV and I came up with a LG - 37" 1080p Flat-Panel LCD HDTV. It finally arrived (was supposed to come in last Friday) and I just got done setting it up.

    I have just a couple of questions. I hooked up our old "bunny ears" and ran the auto tuning sequence. It reached out and pulled in and stored 36 channels in various bands. I watch virtually no broadcast TV, but just in case I want to view the latest episode of "House", is this going to go "bye-bye" when Analog does in the middle of February? Will I need to go out and buy an HDTV antenna?

    I hooked up the DVD and it works like a charm. Slipped in a M*A*S*H DVD and noticed that the picture was all stretched out. I set the aspect ratio to "scan" hoping it would autodetect the DVD's needs but it didn't (worked well for broadcast TV as some stations came in at the old squarish ratio and others in wide screen). So my wife could watch the DVD, I manually set the aspect ratio so it would provide the best viewing for her show. Does anyone know if I'm missing something here as far as the configuration?

    BTW, I read through the manual, which I found to be more or less adequate, but it could have been better (the steps for putting the stand together left out a lot of steps which fortunately, I was able to figure out). I checked the specs online and went through every menu I could find on the TV itself searching for likely settings.

    Beyond what I've mentioned so far, it works like a dream. Set up wasn't really that difficult. I'm just not used to the whole digital TV thing, so it's all new to me.

    Anyway, let me know what you think. Thanks.

    Trip was teh DVD player and old one? a lot of newer DVD players do what they call upscaling (filling in pixels basically) to produce a viable looking hd resolution. Your DVD player probably only outputs SD. ALso was teh DVd format 4:3, again most HD TV's display a standard pic of 16:9. You should be able to change this ratio in teh TVs menus. This is teh more likley case of the streching. I know our old TV had formats of 4:3 16:9 and what it called widescreen which streched the pics.

    As for teh Analog being turned off. I know here in teh UK its already going of in some counties. Which means if those people dont have some form of Digital reciever (SKY, Freeview etc) then they cant watch any TV. I'd assume it will be the same for you. Now some LCD Tvs have built in Digital recievers so all you need is an areial capable of picking up teh digital signals, best ones for that are external areials as well. Your manual should tell you if yours has this built in.

    HTH i hope.

    As you can see you're ok for the digital service when analogue goes.

    As to the dvd - assuming this is not a brand new one capable of playing ND DVD or Blu-ray then there won't be any upscaling but that's not the issue. It will play just as it always did and the set should detect the widescreen aspect ration. If it isn't then it'll be a setting under one of the menu options on the LG or it could be your scart lead (check you have one with all pins fully wired to ensure that scart-switching works ok). This should then pickup the signal from the dvd player and display it correctly.

    Only other possibility is if you bought the dvd outside of the USA so it's not Region 1. If that's the case then that could be causing it to have a problem with displaying. It would be unusual and the set should sort it ok but it may need setting manually.
