Questions on MPC-HC/BE, LAV audio filters
I'm not exactly a noob with this stuff - I've had an HTPC setup for a few years with MPC-BE, LAV Filters, bitstreaming DTS-MA/TrueHD etc - but I'm far from an expert, I haven't kept up with developments and my hardware setup is a few years old. Other than occasionally updating MPC-BE, running Windows Update and setting up a simple Samba server with a PogoPlug, I've changed almost nothing with my system for 3-4 years (thus didn't notice when MPC-HC started using LAV filters as internal audio filters)
But now I'm having some trouble, and think I may have messed up my MPC settings somewhat. I probably should just start from scratch and try to get things running smoothly again. Questions:
[background for all questions: my system is not remotely cutting edge - Win7 x64 on AMD Athlon X2 BE2300 1.9GHz with 3G DDR2 ram, with AMD HD6450 video card, INFOCUS IN72 projector that seems to handle 720p & 1080p material fine but is itself only 480p]
1. When I first set up my HTPC I believed that there was no benefit to using 64-bit versions of MPC, LAV, etc, so I used all 32-bit. Then at some point a couple of years ago I switched to MPC-BE and started using 64-bit everything. Is there any reason to switch back to 32-bit software? I don't know if 64-bit has been causing me any problems, but I do think that my system is operating close to its red line and I occasionally get a random video-freeze or the video I'm watching gets jumpy or speeds up.
2. Is there any reason to ditch MPC-BE in favor of the original MPC-HC? (again, as far as I can tell MPC-BE 64bit has been OK)
3. I had things set up to explicitly use LAV audio filters. But my understanding is that MPC now uses LAV by default - correct? What do I need to do to program MPC to use its internal LAV filters? (and I presume that I no longer need to worry about keeping LAV updated since it's included in MPC?)
4. Am I correct that with a relatively old/slow system MadVR would be too resource-demanding?
Thanks for any advice/guidance...
