    I have downloaded 2hours-5minutes of self shot SVHS footage from my VCR through my digital video camera (To be edited completely with NERO 6.0.18(?)-not the most current version). With a quality setting of "Automatic", this program tells me it is 3.23 gbs'-if I manually set the quality to long play, that figure changes to 2.90gb's.I have tried to burn a dvd with both settings, with the same results-After about 6 hours, a screen pop's up saying that I should put in a dvd disc (which I had already done before starting the Transcode/Burn process.) I then have tried 5 disc's(Maxwell) (of "-R"-my machine handles "+" or "-" with no problems))-All did not get recognized-As this was a new "sleeve", I thought I might have a bad batch, so I unwrapped a brand new dvd-RW disc(Fuji)-still did not get recognized. It then "(after)DAWNED" on me that because this data was 2hrs/5mins that maybe I needed a dvd-5 or -9. My dilemma is this; The amount of disc space needed in either of the above scenarios was (supposedly) 2.90 or 3.23-well below the 4.78 the disc(s) is supposed to hold. Is it possible that due to some NERO setting it is not reading the data correctly? Should I buy a DVD-5/9 as I know the total data to be too close to what is the normal max for a standard dvd? Should I just re-edit, split the chunk of into 2 and burn 2 dvd's?-Should I use dvd-shrink (or related program) to make it fit?-I'm not even sure I can buy DVD-5/9 in retail-I've never needed one before and have never looked for them.Any advice is much appreciated. Thank you.

    Although I know what the "KISS" (Keep it simple, stupid) principle is, I tend to over analyze things. I burned a disc last night, no problems. The cause of the earlier problem was that I had set the burn rate to MAX from what has always worked-4X- I am a faithful reader of Afterdawn and I do know better than that..So not only is this a "My bad" scenario, it is actually more of a "MY STUPID". Problem solved.

    Since your master is S-VHS, keep the automatic setting with 3.23 GB for less compression/better quality than 2.9GB. (The difference may not be visible, but 3.23 is a better choice.) These are binary calculations; so you can only expect 4.37GB on a DVD disc in binary terms. The 4.7GB is a decimal specification. The difference between the two is that computers count by twos, and a thousand is 1,024 (two to the tenth power). Humans count by tens because we have ten fingers. A thousand to us is 1,000; so our decimal numbers tend to be larger than the binary "equivalents."

    A DVD5 is the same as a standard DVD. The 4.7GB in decimal terms is rounded up to an even 5. A DVD9 is a double layer disc of 8.5GB decimal/7.96GB binary. It is less than double the size of a single layer DVD because the pit marks are increased 10% for easier tracking. It all gets very confusing.
