Hi,
@Uwe (DerDumeklemmer)
I noticed you had changed my message by converting URL's to embedded streaming objects.
I tried using them too, but embedding the first part of the video is disabled by request in YouTube, so I decided to provide both as URL's only.
If you tried to start viewing the first part when it was an embedded streaming object it gave you 'false' message stating the video doesn't exist any more.
Now it is a compromise - first part URL, second part embedded streaming object and both work now.
Cheers,
Timo
