I have a digital tuner hooked up to my pc. For every show that I like I have one DVD+RW disk that I store episodes on. After I have recorded an episode, I edit out the adds, convert the MPEG files to AVI, then store it on the DVD+RW disk. As the series is shown on tv over a long period of time, I have many partial filled DVD+RW disks of episodes. Once full I then copy them and burn them to DVD-R. Rinse and repeat for the next lot. The system is simple and works well, allows me to find what I want easily, doesn't waste disks and helps ease the burden on the hard drive.
My point is not to say the author of Imgburn MUST include multi session... it is his program and he is offering it for free, and I respect his wishes not to. I am however challenging the assumption that it doesn't have it's uses... as I think other people in this thread also have.
Anyway, I felt compelled to create an account and comment on this as when I searched google for imgburn and multisession DVD this thread appeared on the first page. I thought if enough people actually say that it is useful he may consider adding it (as otherwise it appears a great program.) In the mean time I have found CDBurnerXP which appears to support this and might try that out.
Thanks.
