Post subject:  Most reliable mytharchive setup/process

Mytharchive problems.

Very often, there is some error which screws up the whole process.
I gave up making chapters, as often that would cause an error and the iso could not be created.

Below, I think there was an err in the AC3 stream; so it made an iso of the first 58 MB out of 2.3 GB.

I checked to always use ac3, and always run mythtrancode, and don't use chapters. Is there anything to make this process more robust?

Thanks.
