When CXD says it’s 4.47GB, it is oversized and won’t fit on a DVD5. The maximum size on a DVD5 is 4.37GB in computer’s view. 4.7GB is marketing term. Read HERE to know more about DVD sizes.
Original file sizes have nothing to do whether they will fit on a DVD, it’s the total playing time that matters. What does it say in the status bar of CXD? The more you put in, the lower the quality. Because your source is AVI, it is highly compressed, so when converting to DVD, which is not highly compressed, the output size will always be larger. With this said,
No, you cannot. Since you want to squeeze as many episodes as possible, it’s best that you use the “Low” quality setting for best output quality.
Here’s the rule of thumb for best “quality” setting based on project length:
My second question is (it might have just been the discs I had) but I had some DVD-Rs and ConvertX would not burn whatsoever to those discs (don’t know the brand, a friend gave them to me) but then I got some Memorex DVD+R and they work perfectly. Any ideas?
You probably have low quality media. Use high quality media (Verbatim, TY) or whatever that your burner likes.
