Comments, please While this may actually help in your case, I'm not particularly fond of this. The cDvbPlayer shouldn't have to worry about this. It takes care that data is sent to the player device fast enough to avoid underruns, but that's all it should have to care about. It's the device's (driver and firmware) job to play the data correctly.
From what he's saying, the problem is buffer overrun's, not underrun's. Too
much data is being sent and the device isn't able to keep up. If that's the case then it would make sense for vdr to have a user setting to limit how many seconds (or milliseconds perhaps?) worth of data is sent to the buffer. I can't think of any reason not to add such a feature if it means better usability for the end-user. That's my opinion anyways.
