SRT lose sync with dual-core CPU

[engnz]

I just upgraded my CPU to a dual core. All other system hardware unchanged.

Since then the SRT for all my recordings gets progressively out of sync. Seems to get worse if I'm watching an old recording while doing a new one.

Searched the various threads on SRT and tried using srtmod.exe but didn't work very well.

I rechecked my old recordings and the SRT subtitles still playback perfectly so I believe that the dual core is causing my current problems. Is the some kind of timing problem when recording on a multiprocessor system? Any ideas on how I can fix it?

I've been trying to resync my SRT files using Subtitle Workshop. However it doesn't read the dvr-ms file which I record in. When converting to mpeg2 I see a strange error that the video stream is 35.08fps. (see FFmpeg output below)

Is this a problem with the Freeview DVB-S broadcast or the way that gbpvr.exe recorded the dvr-ms format?

Were these SRT files recorded in GB-PVR? If so, was it from a digital device or an analog device?

[engnz]

Yes gbpvr.exe 99.12. All Freeview digital from Teletext page 801. They sync fine in the past until I upgraded my CPU to dual-core.

I havnt tested this in a while, but I'll note it down to give it a good test for the next release.
