I'll recommend Software Engineering Radio (http://www.se-radio.net/). The interviewers are a bit uneven, but the topics and interviewees mostly interesting. A vast backlog, too!
Other than that, my main source of information is youtube videos coverted to mp3 using `youtube-dl --extract-audio --audio-format=mp3`. Possibly your podcast player can treat regular mp3s as podcast episodes (the wonderful PocketCasts on Android supports this: http://www.shiftyjelly.com/support/pocketcasts#115)
SE Radio is definitely a great podcast. I'm not even a professional developer (Linux sysadmin) and I find at least 1 episode in 3 fascinating. They do a good job of keeping the topics diverse.
I agree that sometimes the interviewers (or the recording quality itself) can be a little weak and difficult to understand, especially on older episodes. That seems to be pretty common among podcasts, actually. I dislike and/or disagree with the host, and the production quality sucks, but they get such outstanding guests that it doesn't matter. I used to listen to a lot of podcasts on homebrewing beer, and that was definitely the case in that world.
