Talk:Using a RAM drive for the live TV buffer

I followed this guide on Windows 7 Home Premium

I have 3 tuners (HDHomeRun Prime), edited the registry for a duration of 5 seconds, and 4 buffers. Used SoftPerfect RAM Disk to make Z: with usable capacity of 478mb. Article says I need 447.5MB. Put the TempRec link in place.

on boot, I had Z: with /TempRec and 478mb free

after starting WMC almost all Z: was used

after selecting LiveTV -- immediate DISK FULL

same result when using 500MB, 1000MB, 2000MB just took a little longer before the DISK FULL

Any ideas ?

an update:

using 3 tuners, with the registry edited for 5 second duration and 4 buffers, but using a 2TB disk for Recorded TV and the LiveTV buffers, after watching a while, here are the buffers and creation times from TempRec/TempSBE

12:11pm    522,992,280    510,740kb

12:11pm    522,992,280    510,740kb

12:11pm    522,992,280    510,740kb

12:11pm    522,992,280    510,740kb

 01:38am        6,815,733        6,565kb

 01:38am        6,815,733        6,565kb

 01:38am        6,815,733        6,565kb

 01:38am        6,815,733        6,565kb

01:38am    522,997,280    510,740kb

6656/5 = 1331 kb/s is a reasonable data rate for a 720P broadcast. Note: one of the rolling buffers is being allocated at the MAX size. The total buffer size 2,580,332 kb
