Hey, just wondering whether ISO or M2ts formats are flagged to be supported in the near future for the DVR. Thanks

Assuming by M2ts you mean a MPEG Transport Stream (MPEG-TS) container with a video stream encoded in MPEG-2/H.262, then the answer is emphatically Yes. MPEG-2 video in a transport stream is the native format of OTA broadcast TV, Channels' first format.

Have you tried renaming your files with a ts or mpg extension, which most media players expect?

Right understand. Renaming it to ts does the trick. Thank you!
