as pointed out by Nimajneb in the [Fixed] gPodder 3.3.0 asking to install Python thread here gPodderPortable_3.3.0_Rev_2 changed the download location from
gPodderPortable\Data\config\Downloads
to
gPodderPortable\Data\downloads
I installed gPodderPortable_3.3.0 a few days ago (XP SP3 Home), downloaded a few podcasts, upgraded to gPodderPortable_3.3.0_Rev_2 and the couldn't see the podcasts in gPodder Portable.
They are still on the drive in the old download location, just not showing up in gPodder Portable.
This issue is fixed in gPodder 3.3.0 Rev 3. Your two existing download locations (for users who upgraded) will be consolidated to Data\config\Downloads.
Sometimes, the impossible can become possible, if you're awesome!
Thank you John
