If the used Tv Backend supports Timeshift then it's usable in XBMC. E.g. if you use MediaPortal TV Server, MythTV or Argus TV (formerly known as 4theRecord) than you have Timeshift. With e.g. TVHeadend you did not (now) have Timeshift...Is it possible to enable timeshifting with multi seat?
The XBMC MP plugins handle all this.How can you use TSReader over wifi? Isn't whole point of TSReader that it reads timeshift files directly from server folder?
