I'd start from scratch personally. You'd have to sacrifice a little functionality (at the moment) but you'd greatly simplify your setup (reduce the number of cards and downsize to a single computer) and it would let you run on the latest hardware so you aren't having to build around legacy devices or limiting your hardware options. Plus it's a super simple, centralized setup.
Starting from scratch is something I may do and pretty soon. Now, timeshifting really is something I don't want to give up even temporarily. MyHD's app lets me do that adequately, and I'm told that I can use that in tandem with the HD Homerun dual tuner unit. Many MyHD users have gone in this direction. As soon as I identify a PVR solution that allows me to timeshift and with remote contol, I figure I can abandon the MyHD hardware/software and move to Windows 10 and probably even 64bit, I suppose.
Plex Media Server is something I've been hearing about for a while. People say it is great. I've never seen it, though. I'm sure it is great. My NAS is a Synology DS214play, and it's possible to run Plex with it, but Plex doesn't support that NAS's hardware transcoding. It may not be an issue for me, don't know. I don't have a 4k display system, just 1080p.
Right now, I watch HDTV, usually timeshifting or else watching timeshift-recorded programming at a later time. The MyHD app AFAIK always records currently broadcast transmissions while displaying whatever you're watching (i.e. anywhere within the whole recording). When I'm done watching I just bulk erase the buffer and start from scratch later. Or, I sometimes keep some of my buffer for later watching. I have a program I wrote that tidies up the buffer (what I've left in it) and subsequent timeshifting gets added to the end.
Yeah, I guess I need to leave the PCI cards behind me.
I have an SATA optical drive that I've never used, it's not Blu-ray though. I didn't use it because it wouldn't work in that system! It was crazy. I posted here and an AT member sent me his unused IDE DVD burner, and that's what I'm using. This happened because my other IDE DVD burner crapped out. I bought an SATA burner to replace it, but I've never used it.
I just ordered an
EVGA 500 BQ PSU. It's newly released, haven't been reviews yet, but I like that it's only ~$50, is semi-modular, has FDB fan and 100% Japanese capacitors. I ordered it today because I think the PSU in my main system here (the Corsair) is losing it. The last couple weeks or so the machine won't come out of suspend. Doesn't seem to start from a complete shutdown unless the plug is pulled and reinserted first. A new PSU ASAP was high priority.
