Oh, cool! DIdn't realize there was a newer version.
Re: your question...I haven't applied the newest fw update yet, and I don't recall when the 2.12 was installed (I don't think I've allowed a firmware update since I started using Tablo in January?)
Also, the file I chose for the debug was simply the first one I noticed the problem with. I got rather random results with other show-files since then, some extract just fine, others fail, within the March/April time period. Roughly two weeks ago, I discovered that my Tablo had locked up, requiring a reboot. Since then, new recordings have been made, including yesterdays SNL which...is exporting successfully! I also successfully exported some Charlie Rose segments recorded since the crash.
So, maybe I'm good after the reboot? But does that mean the pre-crash files are likely lost for good? They play back fine in the Tablo web app.
Anyway, I'll take your advice and dl the latest build. Thanks for your help!
