I have adjusted tuner priorities so the HDHR is preferred over the pvr500 card. Also the pvr500 is in a different video source than the HDHR prime so I am able to manually rerecord programs from the upcoming recordings page of mythweb. I want to know is there an easy way to make this automatic. Can I flag groups of recordings to rerecord. 

I did something like this for a friend who wanted to upgrade her collection of favourite House episodes from analog cable to digital OTA. On the digital channel we did a record all this channel and for duplicate matching we said only in current recordings & gradually her faves are being upgraded. I also did a SQL report to mail her a list of duplicates every week and she manually reviews and deletes. The key here is the digital channel is different from the analog one.

I imagine this could be made generic with a custom query that selects your desired titles when they appear in the new source and a row exists with the same programid and the old source. That involves a lot of hunting so I doubt this would perform very well.

Since the list of shows to rerecord is static(ish) you might instead get their programids and do a custom query matching on the new source and programid in the giant list of IDs. I assume programid is indexed so this would run efficiently.
