I have been having problems lately with Nero reporting 'failed to write end of disc-at-once' when trying to burn. This has been driving me nuts, as at least 1 in 2 DVD's was not burning.
I then stumbled across CopyToDVD (a demo of which can be downloaded from www.copytocd.com) and I have not yet had a DVD fail to burn! It is also really easy to burn to DVD-Video - No 'ISO/UDF Paritioning' to set, just select 'File --> Write DVD-Video' and away you go!
You still use DVD Decrypter & DVD2One (or your chosen compression tools) and then use CopyToDVD just to burn it. It takes around 1hr30mins to create a 'cached files' and to burn it, but as I said, no coasters yet!
Even if you dont like it, it must be worth a look :-). Ler us know what you think.
However be careful because the new updates now check to see if you have a valid serial no. if you don't you will only get the update in demo mode.
I know cos I found my serial no. was invalid and contacted ahead they said my version was likely to have come from an unauthorised source, I binned it then and purchased recordnowmax from orlogix.com, no problems with this and better than nero in my opinion.
