[QUOTE="mm1352000, post: 1171525, member: 82144"] Hmmm, that's interesting because the maths doesn't add up. The dxdiag log tells me that the E: drive has 6.2 GB total space, but only 1.5 GB was free. This was the status [I]after[/I] BIGBOY's stream had stopped. I know from the TV service log file that BIGBOY's stream had 3 time-shift files: [collapse] [2016-01-13 18:28:29,391] [Log ] [TS_File_Cleanup] [INFO ] - card: delete timeshift files E:\\live9-3.ts [2016-01-13 18:28:29,391] [Log ] [TS_File_Cleanup] [INFO ] - card: trying to delete E:\live9-3.ts.tsbuffer [2016-01-13 18:28:29,391] [Log ] [TS_File_Cleanup] [INFO ] - card: deleted file E:\live9-3.ts.tsbuffer [2016-01-13 18:28:29,391] [Log ] [TS_File_Cleanup] [INFO ] - card: trying to delete E:\live9-3.ts.tsbuffer1.ts [2016-01-13 18:28:29,438] [Log ] [TS_File_Cleanup] [INFO ] - card: deleted file E:\live9-3.ts.tsbuffer1.ts [2016-01-13 18:28:29,438] [Log ] [TS_File_Cleanup] [INFO ] - card: trying to delete E:\live9-3.ts.tsbuffer2.ts [2016-01-13 18:28:29,453] [Log ] [TS_File_Cleanup] [INFO ] - card: deleted file E:\live9-3.ts.tsbuffer2.ts [2016-01-13 18:28:29,453] [Log ] [TS_File_Cleanup] [INFO ] - card: trying to delete E:\live9-3.ts.tsbuffer3.ts [2016-01-13 18:28:29,500] [Log ] [TS_File_Cleanup] [INFO ] - card: deleted file E:\live9-3.ts.tsbuffer3.ts[/collapse] 3 x 350 = 1.05 GB 1.5 - 1.05 = total space available when BIGBOY was trying to change channel = 450 MB That number seems right because in order to successfully start time-shifting, TV Server requires that there be enough space to create [B]2[/B] time-shift files. What doesn't add up is how only 1.5 GB could be free (and 4.7 GB used) when only MASTER is streaming. Even with a full sized buffer, MASTER's stream should only have been using 8 x 350 MB = 2.8 GB. Is there other stuff using up space on the disk? No, not unless part of the disk space is used for something else. That number is calculated as: (8 stream files + 1 file worth of free space) x 350 MB per file. The "1 file worth of free space" is space left to ensure the disk doesn't ever get completely full (which can be really bad if the disk is also used for the operating system). It would be nice to not have to specify the file counts and sizes, but the maths gets quite tricky. Essentially the mathematical problem is: what is the smallest common factor of 2 numbers which is greater than or equal to [approx.] 100 MB. "Min" is not really a minimum. It's just the standard buffer size when time-shifting. "Max" only has an effect when you pause. When you pause, the buffer size can increase from the standard size up to the maximum size. [/QUOTE]
