This morning when I turned on my TiVo I had a message about having run out of guide data, but it was all there when I looked. I noted a few other changes in the HDUI and presumed I received a software update. It says I am running 18.104.22.168-01-2-746 When I began watching recorded content I noted a significant change. When I tried to fast forward x3 through a commercial and then hit fast foward (a forth time) to resume watching the show instead of the "smart restart" where it would resume playing from the return of the show it just made the "BONG" noise and continues to fast forward. I confirmed with TiVo and they reported that I must have received the latest software update and that is a issue they are working on. Any ideas what else may have changed? I am new to TiVo and wonder how long it takes for them to fix bugs like this.
