Backup 2 DVD movie into one DVD-R

Sort of; you could combine the two video files (say two 30 minute episodes) into one single one-hour episode, with a "chapter stop" (DVD menu item) at the beginning of both episodes.  That would certainly work and is straightforward, just like combining "clips" into a single video.  Remember that movies, which nominally run 2 hours, go on commercial pressed dual layer DVDs, which hold about 9 gigabytes.  Your normal single layer DVD is only 4.7 gigabytes, and thus will hold only one hour of "DVD quality" video.  You can get more on the disc by using a lower encoding bitrate, but the quality suffers.  In my experience, I wasn't happy with 2 hours on a 4.7 gigabyte DVD, about 1:20 to 1:40 (80 to 100 minutes) was as far as I was willing to go, however that may be fine for two 1-hour shows by the time you edit out the commercials.  You could also use "dual layer" DVD+R media if your burner supports it, but it's still hard to get, quite expensive, and I'm not sure yet how "stable" that format it.  [Dual Layer DVD-R will be out later this year, right now all of the dual layer media is the "+" format].

Note, you can't do this [add the 2nd episode] after the DVD is burned; there is no "multisession" for video DVDs.  You could make a new disc that had both episodes, but you can't add it to an existing video DVD and expect it to play on a set-top DVD player, even if the space is available.

There are other alternatives, DivX gets nearly full DVD quality in about 700 megaybtes per hour, so even a 4.7 gig DVD will hold 5 or 6 hours, and you can cut the quality down just a bit -- but still very acceptable -- and get 12 hours on a 4.7 gig DVD.  Problem is, it's not a video DVD and it won't play on most DVD set-top players, only in comptuers with DivX codecs.

I don't know the exact programs to do this, but main idea:

You could take screenshots of each menu, and change the buttons to actual buttons, instead of just sitting there in a screenshot.. i had VCD easy that did it with VCD and SVCD.. easily.. (maybe thats why it was called VCD easy ^_^) but the only DVD burning program i have makes its own menu's.. i hope this helps :)

oh, btw, if you wnat to buy a new dvd player, there are those on the market that play DivX. I saw it on the DivX website a while ago.

As I said, "it won't play on ***MOST*** DVD set-top players".  Yes, there are some (relatively new) DVD players that will play DivX files natively.  Still the exception, however, rather than the rule.

Sorry, I think i didn't make myself clear.  At the moment I have about 10 DVD ..each DVD have about 6 eposide. I'm able to use DVD2One to combine 3 DVD to one DVD-R.  The problem is each DVD have it's own menu ..and when I merge 3 DVD to one DVD-R is it possible to keep the original main menu's?
