Hello all again,

there is an issue when using VLC (any version) to receive an MPEG2 stream 
generated by HDVTS http://www.sfc.wide.ad.jp/DVTS/ both in UNICAST and 

Even if HDVTS generates a stream which UDP should be able to handle 
correctly, VLC cannot display correctly the video, generating lots of 

If you tell VLC to use RTP instead for receiving the HDVTS generated 
stream, the all if OK.

It seems some problem related to VLC UDP implementation not being able to 
correctly receive the HD (28Mbps) MPEG2 stream arriving form HDVTS.

coul you please investigate this issue ?

thanks indeed
