Hi.
I'm looking for solution on issue during launching Xlet from another Xlet after VFS update on Samsung BD-C5500.
The same application runs fine on PowerDVD, WinDVD and PS3.
Here what I try to accomplish:
1. On the disc there is single Xlet (A) marked as first playback
2. Xlet A fetches second one from network (Xlet B)
3. Xlet A requests VFS update (in result there is PREPARED state)
4. Xlet A invokes starting Xlet B
5. On Samsung, after point 4, nothing happens, not going into initXlet, not throwing any error etc.

Tried samples from HD cookbook, the same happens.

As I mentioned before, it runs correctly on PS3 and software players.
Placing Xlet B on the disc (not downloading it and requesting VFS update) makes it working on all players.
Any ideas?

Regards,
Michael

Hi Michael,

Is it working in other players such as Sony BDP - S380?

If it is not working in any player, I suspect it must be something to do with the signing of xlet.

Did you sign both xlets (Xlet A abd Xlet B) using same certificate? If not, try signing both using one certificate.

Hope this helps.

Regards,

Ramanan

Ramanan,

Did not try on Sony BDP-S380. I just ordered 2 additional hardware players, waiting for them.

Yes, both A and B are signed with the same certificate :-)

Hi Michael,

Given what you're describing, it seems to be a player issue and not your application problem. I vaguely recall that Samsungs have a problem with VFS Update related functions operating from BD-RE and BD-R discs. If app A is on BD-ROM, then I suspect it'll work.

Chihiro,

If I place both A and B on the disc it works.

It A downloads B and then A runs VFS update and tries to launch B, it does not work (no exception, message etc.

If it is Samsung related issue, then I assume that there is nothing much to do with it :-)

Maybe I should try to contact Samsung directly, what do you think?

Ok, here's a past thread about this Samsung issue.

You can contact Samsung, but it's not really a bug, that it's hard to imagine Samsung updating this part of their player requirements....
