Having the exact same problem with largeish (50-something mb) mp3 podcast files from the CBC (Canadian Broadcasting Corporation). They play for the first 15-20 seconds and then a "File format not supported" message appears and the device skips to the next track. These are on the internal memory of the device, and besides that I'm using a Class 4 microSD card for other files.

Correction: the files this has happened with actually play for 33-34 seconds. Not every CBC podcast file is doing this. Just did firmware update 1.17 (since my last post)—didn't fix the problem.

What bitrate are the 50MB podcast files? For voice recordings, imo 32kbps MP3 mono is probably the best choice, as higher bitrates don't improve the sound of voice recordings much. While 32 kbps wma files sound a bit better than 32kbps mp3 files, playing WMA files seem to consume more battery power and give shorter run times. Using 32kbps mono instead of 128 kbps seems to give me at least 10% more run time per charge.
After I download podcasts, I typically convert them to 32kbps mp3 mono if they are at a higher bitrate. Some podcasters are now using 32kbps.

I just bought the Sandisk and used windows media player to populate the Sandisk 32G memory card. My files are .wma and some play while others don't? I get that same "file format not supported" and then a screen appears as if it were trying to play, but there is no progress across the bar and no sound. It displays the correct album/song info, but shows a 0:00 length. Has anyone else had this problem?

Are some of the files (the ones that don't play) 'protected' (aka DRM-encrypted) .wma files?

I get this with everything. I use the ogg-vorbis file type for my music that I ripped from CDs. Every song is 44100 Hz sample rate,140 kbps bit rate, downmixed to mono.

I had posted in this thread before and my issue was solved with the 1.22 firmware update found here:
Even if your player is new go to "Settings" >"System Settings"> "Info", and verify your firmware "Version". If it is not 1.22 then update.
I hope that helps solve your problems!

I get this issue occasionally, even with the newest firmware update. It generally happens with .mp3 format podcasts (since I usually put those on the external card), but without fail the problem's just been that the card has become slightly unseated - it seems to stick out quite a bit more compared to the older player models, making this happen more frequently.
Ejecting and replacing the card has fixed the problem every time (also, hitting the 'back' button repeatedly can usually break the player out of its scan through every file on the card).
