Buffersize and NumBuffers for MpegDeMux in registry -- still effective?

[salsbst]

I seem to be having a general problem of frequent (but not constant) choking points in SageTV v6. Specifically, every few minutes, playback halts (as if we'd paused it), then stutters once or twice, then halts again, then starts up again. This takes about 10-15 seconds and then things are fine again for a few minutes. It seems to affect HDTV more than SDTV.

I'm wondering whether we're running out of buffered video. Our HDTV comes from a different file server than SDTV.

I want to try to optimize the buffer size. Back in the day, we had a recommendation to set icrease Buffersize and/or NumBuffers the MpegDeMux in the registry in order to solve stuttering.

My questions are:

1) are these keys still used?

2) let's say I've disabled tssplitter.ax because it prevents playback of certain files... are these keys used in that scenario?

3) if, for whatever reason, some other demux filter (besides Sage's mpegdemux.ax) is used, are these keys still effective?

4) what would I see in the logfile to indicate that athe buffer ran out of data or got low on data? Or is there no evidence at all of this? If that is the case, could we get something in the log file?

I heard back from SageTV on this

1) are these keys still used?

Yes.

2) let's say I've disabled tssplitter.ax because it prevents playback of certain files... are these keys used in that scenario?

Apparently, there's no good reason that tssplitter.ax should be involved in playback, so it is unclear why this would have anything to do with anything.

3) if, for whatever reason, some other demux filter (besides Sage's mpegdemux.ax) is used, are these keys still effective?

No, only for Sage's demux.

4) what would I see in the logfile to indicate that athe buffer ran out of data or got low on data? Or is there no evidence at all of this? If that is the case, could we get something in the log file?

Nothing will show in the log file. I didn't get any sort of statement on whether or not something could/would be logged in the future.
