there is another solution that might work better - 'Remote Channel Stream Converter' have a look in the addon feeds to see if it is there - basically it will give you a virtual bouquet set in the client's bouquet lists - as opposed to you having to go in to a folder and play the created links with the client media player.
Finally, Remote Stream Converter worked perfect in many receivers with several firmwares. It's a great plugin, thank you very much for the info!!
