I would like to see a mechanism that would allow a specific episode of a series to be marked to be rerecorded when the opportunity arises but keep the existing (presumably corrupted in some way) recording until it has been rerecorded. Probably would only work if there is an active pass for the series in question.
A boon for anal-retentive episode collectors.
Create Pass.
Under "Advanced" you can set Season, Episode Number, Episode Name, Original Air Date in any combination.
You just described me. 
The a-r episode collector. 
I use a feature in Olivetin for Channels. "Mark a Movie or Episode for Re-Recording"
I believe that it works for movies and series episodes without an active pass.
there is also a chrome extension for the default server interface that lets you mark things as not recorded from the library.
this is sorely needed in the tv app though, since that's where you watch and find out it needs re-recorded.
Does this work if you don't delete the existing recording? A key part of my request is that you can keep the existing recording until a new recording is made. (And an implied part is the original recording will be trashed once the replacement is available.)
I believe both ways work the same by marking the episode as Not recorded, so it will record the next time it airs. there is no way to automate the delete, and why would you before verifying it's any better. many times I had both airings of an episode air during a storm and both were corrupted, but hopefully in different spots. 
Yes. I always keep the original recording, just in case the new one doesn't turn out well.
Withdrawn. I see that "Mark as not recorded" is pretty much exactly what I want.
