Have had the 4.5 for awhile now and just noticed that Roxio in DM 4.5 is NOT detecting my media card...
Mass Storage Mode is enabled, but miss being able to transfer/transcode videos to my 8320....
Anyone else have this issue or did I miss my setup somewhere???

DM 4.5 isn't Beta anymore...

Suggestions... reboot the BB. Make sure the USB is connected direct to the PC, not to a hub or monitor port.

i asked my question incorrectly......
since upgrading my phone to OS 4.5 i have to UNcheck mass storage mode in my 8320 options-media card with DM 4.5 in order for Roxio to see my device's media card as connected. A problem with the OS???
If I UNcheck mass storage before connecting via USB then it's detected...it didn't used to work that way with OS 4.2.....better question now?
