I know jachin99 that's why I am here! JRiver is definitely the best media player available today, but in order for me to complete my migration to JRiver I must find a way to import the 'Collection Number' tag from My Movies... and I found out it was not a simple task. I have a collection of more than 6000 DVDs and Blu-rays and they are all organized in a giant cabinet by ascending Collection Number. I need that number to be displayed somewhere on JRiver for me to be able to locate the physical media.
I don't know if this will help but my best try was using the feature "Search and Replace" of "UltraEdit" software. Since all my media is stored in the same folder on a NAS, I commanded UltraEdit to search the term "</Item>" inside all "JRSidecar.xml" files that 'My Movies' have created, and replace with something like: "<Field Name="Catalog #">0001</Field></Item>". But I could not make number 0001, for example, a variable and all my titles ended up with the same Catalog #.
I also tried to use the expressions feature on JRiver but no success.
