[QUOTE="elsmandino, post: 720856, member: 111675"] Fantastic - thanks very much for all that. I note your points about time shifting. So ultimately, for the best performance, I need to avoid putting the time shifting on a different place to that of the recordings. I note that say that this can be done in different ways - either put time shifting on a dedicated hard drive or use RAM Disk. Can anyone recommend which might be the best option? As far as I can see: RAM DISK - much quicker than hard drive though much more expensive than a Hard Drive per GB - cooler, less noisy and uses less electricity than hard drive, limited in terms of how much RAM motherboard can take. Hard Drive - Opposite to the above. I also note that if I went the RAM DISK option, 8 GB should be enough overall to include three client's - how much of this would be dedicated to RAM DISK? I am proposing to have a trial run with my current HTPC, connected directly to my main telly, to see if Media Portal all works out - until I build a new server. Athlon II X2 240e M4A785TD-M Evo NSK2480 Case with PSU 4GB TW3X4G1333 C9A Corsair Ram (2x2GB) 1.5TB WD Green (AV-GP version) Windows 7 (64-bit) Hauppage HVR-220 twin freeview tuner card Nova S2 freesat card As I only have one hard disk, I shall try the RAM Disk option - will there be enough RAM (only 4GB in total) to watch live telly straight of the machine and also stream to one Revo or is this pushing it? Thanks again for all your help, it looks that is gonna be a great set up. Sorry one other quick thing about RAMDISK: Is this a pool of memory that can be used by any of the tuners or do you have to proportion a tuner a set amount of the RAMDISK space? (sorry - hope that makes sense?). If I, for example, have four tuners and 2GB or RAM space, is it the case that: 1. the tuners all share the 2GB of ram, so if two people are watching live TV, they get 1GB of buffer each or 2. You have to preset a certain amount of space that each tuner can use for buffer - i.e you would allow 512MB for each of the tuner). At a guess, I think (he says) that it must be the second option because (with option 1) if you have a single tuner using the full 2GB of RAMDISK and then suddenly a second live TV stream comes in, is Media Portal sophisticated enough to suddenly halve the buffer being used by the first tuner and allow it to now be used by the second tuner?- I might be absolutely wrong about this! I would appreciate confirmation as to which option it is. Sorry that my questions on this are getting a bit technical - I note that there is a bit of a trade off, in switching from Media Centre to Media Portal, in that it is a little more complex to set up given the additional options. Hopefully it will be all worth it in the end!
