Having duplicate channels is an advantage.
As stated, I totally disagree. Seems that duplicating might have some advantage on knowing what app (channel) is having issues. However, if copying the same source, as what appears to have happened, made everyone lose channels that they love and watch. These channels may not have been on long, but clearly are missed already. If that were not the case, I wouldn't see various notes in the forums about them being gone.
It's not copying to THINK AHEAD and USE DIFFERING SOURCES, so that when channels get pulled, whether from the cable or satellite operator/content provider and then the encoder to the internet, the viewers/Roku consumers do not get ditched in the process. Tensen so far has the right idea, just not employed enough, by the ".1's" and the ".2's" he uses. It also might help for each app (channel) to use their own separate pool of streams/sources.
However, one must be careful. Reason being for this, FilmOn's legality battles, which made it change. If FilmOn has legal issues and must pull a channel, a secondary and potentially a tertiary stream/source may be gone. And if it's the only source that works, it will be lost. We also must not forget about cease and desist (C&D) issues causing loss of channels too.
By repeating FilmOn, MB may be taking a step in the wrong direction, if repeating is not permitted in the written form. Therefore, MB must be very careful. Same for any other sources that can be identified as retransmitted or repeated easily (by a watermarked bug/logo). Even though they are online and originated by another source. It's similar to the RIAA and users downloading MP3's and AVI's. They get fines for accessing, not just giving access to them. My suggestion: don't use watermarked channels to link to, to avoid this issue. I don't want the last of the BBC's to be gone forever.
Google "Richard O'Dwye" for info on this. Great example of the last part. Being extradited to the US for a potential prison sentence for linking TV and Movies on a site.
Be careful tensen!
Cut the US TV TAX... Stop Cable TV! The FCC doesn't need anymore of my monies! I don't need anymore watching restrictions/channels pulled, due to YOUR OWN money arguments with stations!
