Recording playback skips

[mshoemaker]

I wonder if anyone has any suggestions for me. I am running Kodi on a Raspberry Pi 3 with OSMC, connecting to a MediaPortal 1 server. On the Pi when I go to playback a recording all starts well, but at the first commercial playback freezes on a black screen for several minutes, then when playback resumes it skips a fair bit of the program. Each additional commercial is similar in that most of the commercial, and sometimes several minutes of the show are skipped. When I run Kodi on a PC to watch the same recordings playback is much better with commercials skipped pretty much correctly. Anyway to disable the commercial skipping, or figure out what might be happening on the Raspberry Pi??
