I am trying to use Rebuilder in conjunction with my Panasonic DVD recorder to efficiently record videos onto DVD. The process I am using is as follows. I have copied the original data from a Panasonic DVD recorder onto the PC on two disks. I'm then using the Womble editor to edit these together and create a DVD image that is slightly too big to fit on a single sided DVD. It is this data that I am using Rebuilder on to reduce its size slightly so it fits on one disk.
Normally this works fine.
But sometimes when I use Rebuilder, I get "dropped frame"s in the output and the file size is much smaller than it
should be. What seems to be happening is that the HC encoder is crashing during one of the phases. When I repeat the test, it fails in exactly the same way, at exactly the same time and at exactly the same place and I get the identical result. This suggests it isn't some slight hardware timing problem related to memory accesses or something else like this, as presumably this would not give identical results every time.
I have taken the source files from one example of this and transferred them to a friend's PC. He has run Rebuilder and doesn't get this problem, the program completes normally. I therefore conclude that the problem relates to my PC or its setup in some way. Interestingly both PC's are the same manufacturer (Mesh) although my friend's is one year older so a slightly inferior spec.
Interestingly, a few times I have started from a sequence that is identical to one that fails except for the fact it either has one extra frame on the end or one less, and with these so far Rebuilder runs fine each time, even though the HC encoder crash occurs on one of the middle phases not the last phase.
Over 30+ experiments Rebuilder runs successfully on about 80% of sequences I try it with on my PC. We have yet to see it fail on my friend's PC and he has run 20+ tests. Obviously I can work around this problem by adding or removing the odd frame, but it is very time consuming to run Rebuilder more than once to try to find something that works.
Does anyone have any ideas on what this Rebuilder problem could be due to and how I could get 100% success?
