Playing UDP mutlicast stream doesn't work anymore

[mihies]

Hi guys,

Since 0.8.6 version I can't play multicast streams anymore. My OS is Vista x64 and I have dual network card config, the iptv one placed on top in adapters and bindings config.
Note: bottom half of the output is writter after I press STOP button.
Any ideas?

Thanks
