Take it back. I don't trust display models. I also don't like the combo models but I understand why you got it. They are a lot more complicated and confusing.
I recommend you save some big times bucks and buy the Panasonic basic DVD-recorder, the DMR-ES20, which is probably the same unit you now have except without the VCR. Here is a price of $149 after rebate. Don't be afraid to buy online. This photo/video dealer is one of the best in the counrty. I buy lots of photo gear from B & H Photo & Video, they are tops in customer service and are rated 5 stars.

Then for the VCR you have two choices. You can borrow one from a friend. If you don't have any friends then you can buy a brand new Panasonic VCR here for $59.98.

Now I used to be a math major so I can tell you that your total price is $208.98, (plus a small shipping charge and no tax unless you have a Office Max in your state) a savings of $10.02 from your current situation. Plus you now have two brand new units with everything included. When you are finished dubbing you can put that VCR in storage or sell it for $30. You now have only a single DVR which is much nicer and with not all that VCR crap on your remote.
I buy tons of home theater, photo and computer gear online. If you want other prices go to www.pricegrabber.com and search. Only buy from 4 or 5 star dealers (a huge company like Office Max is an exception to the star rule) with more than 100 ratings. Use only a credit card and you are protected for 60 days.
Hope this helps.

I just bought the above DVD/VHS recorder as a "floor model", without a manual or remote. I paid $219. at BestBuy. I was able to download the manual online, but wonder if the remote control is necessary to use all functions.
I have not connected it to my TV as yet, and after reading the reviews on this site, am wondering if I should bother trying to use it, or should just save myself lots of frustration and return it. Everything I read appears to be negative!
I bought this because my JVC VCR died and I wanted to transfer my VHS tapes to DVD. I have just a small Sansui TV with DVD player, but used my JVC VCR to tape my mini dv's from my camcorder to VHS.
Can anyone offer advice about my chances of using this without the remote, and/or any other help to a total novice?
Many thanks in advance for your input!
