Resume stopped working

I use to be able to resume an avi movie but not anymore.
Serviio 1.3.1 via Ethernet cable to Xbox 360 to Pioneer TV

Have I somehow turned off resume and if so how do I get it back ?

There is no setting. It's possible that the XBox doesn't support it for all files and your avi file might be affected by this.

Has been working fine for 2 years...stopped working about a month ago.

Still have not got the resume working....1.4.1.2 version of Serviio

One day later...finally success
Setting in Xbox itself...Xbox video...resume ....an Xbox update must have changed it
