"forgets" about downloaded podcasts?

I recently downloaded DoggCatcher 1.1.973 on a Sprint HTC Hero. I have one manually added podcast feed that publishes a new item about once per week. Each download is on the order of 150MB.

Several days ago I downloaded the two most recent items from this feed, and all was good. I have been listening to them over the past several days. However, this morning, all of a sudden DoggCatcher no longer thinks the items have been downloaded. If I tap them, it wants to add them to my queue.

I have not changed any settings or made any other changes in the app over the past several days. No items have been added or removed from the feed either, as far as I can tell. The downloaded audio files are most certainly still there, because I can still see and play them with the normal Android audio player (I have "media scan" enabled).

Any idea why this could happen? It's quite frustrating because these are very long podcasts, and it is rather inconvenient to lose my place in them.

Filenames changing

What could be happening is that the filenames of the media files are changing in the feed coming from the publisher. You would be able to tell that this is happening if you downloaded the files again and then looked at the sd card. If you see more than 1 copy of each file there then that's what's happening.

DC determines that the file needs to be downloaded by looking at the sd card to see if the file is there or not.

Thanks for the feedback. I

Thanks for the feedback. I should have also mentioned that the "make filenames unique" option is enabled for this podcast, because it uses identical m4a filenames for each episode in the feed.

As you suggested, I had DC re-download an episode that it had previously downloaded and I checked the contents of the microSD card. There were indeed two identical copies of the file with a different unique hash at the beginning of each filename.

What information does DC use to generate a unique hash for an episode? What could cause it to generate two different hashes for the same episode?

Thanks again for your support.

Uniqueness

It's a combination of the title and the pubdate, which I expected to not change over time...but it seems that in this case they do. That's gonna be tough to work-around. Those are the two fields that are the most likely to not change over time.

Thanks again for the information. I would not expect the title or pubdate to change either. I have saved the xml for the current feed contents, so if I notice similar behavior in the future I can use it for comparison. In the meantime, I'll assume it was a one-time fluke in the feed.
