I'm well aware of the TVE churn going on, but I still find TVE worth paying for. I do however have to frequently update my TVE custom channels m3u because of frequent changes. To do this I have a collection of tools I have cobbled together.
Something occurred to me while doing this: it might be helpful to all of us TVE custom channels users (and perhaps others) if the CDVR server could nightly check the status of my TVE source and give me a report telling me if any TVE channels have become "no longer available" for whatever reason. Also, on the off chance that a TVE channel has returned (as happened here with a recent server update) those channels would also be reported. One nice implementation would be to put the settings for this feature (on/off, where to store the report, is the report summary, verbose, whatever) in the settings for the TVE source. That way, if a user has multiple TVE sources, each one can be monitored independently.
