Errors and starting a recording at live instead of beginning

When recording a show I often want to start watching it prior to the show finishing. Youd think that would mean it starts from the beginning right? WRONG! When you hit watch it starts it at live tv. Needless to say this can cause major spoilers especially when youre recording a sporting event.

Also when watching in this way I get an error periodically and it stops the show making me restart it but once again this makes me go to live tv. Im doing this from home wifi (which otherwise has no issues) so its not a connection issue.

I realize these are all first world problems but come on Comcast were paying you way too much to have you put something like this out and calling it a final product.
