Page 1 of TMPGEnc DVD Author help

I have been using this programme version 1.5.20.62 for about a year with no problems. I use it to convert my RAM recordings made on my Panny to a DVD. Recently while copying the DVD video data I have noticed it sometimes cuts off before the whole of the blue segment bar display has shown that the whole of the recording has been copied. It then misses out the copying chapter info and goes to the Add clip screen. When I play the DVD in my panny only the part that has been copied is there. The whole of the RAM disc recording plays ok on my panny. I have also noticed that when creating a menu the clip (where you pick out the thumb nail) it contains the whole of the video data that has been copied rather than the first few minutes
It doesn`t do it every time and it happens on different RAM disc`s. Any help appreciated

Its proberbly of no help but I use version 1.6.26.73 with my ram discs from my old Panny E50 and dont get the problems you have? I do find that it wont let me add videos of a different quality setting to the same disc. I can get Ulead Video Studio to do it but then it does`nt not like Dolby Digital 2.0 audio!!

I think the only difference is that 1.6 is double sided. I haven`t been having any problems until recently. Tried un installing and and re installing with no improvement.
