Some videos only play after renaming - why?

This is a persistent problem I reported a while back still am unable to resolve:

I download an avi (or mp4) file on my laptop - say it’s called filmtitle.hd264.720.avi. And the PS3 refuses to play it

via Twonky.

To fix the problem I rename the file once it  has been copied over to the MBL. I don’t change the suffix - just the NAME. It could be dog.avi - that doesn’t work so I change it to cat.avi and then it does. What gives? Maddening to have to do it with each transfer.

I’ve updated the Twonky to v.6 but still have this issue. It happens across various files from various sources, both .avi and mp4.

Anyone else get this problem?

Maybe you should try contacting WD’s Technical Support about this. You can do so either by phone or email.

Just curious.

Do this.

After uploading.

Go to UI and rebuild the database.

See if that works, instead of chaning the name.
