I set mine to 120 minutes (2 hours) because the wife paused live TV once to take a phone call, forgot about it, and 45 minutes later went back and was mad that she lost a bunch of the show. Now I can tell her that if she did not start watching it again within 2 hours, it is all her fault she missed part of the show and she understands that yeah, it would be her fault and not the computer's fault. smile.gif

One of the few things I miss about the old Motorola STBs, was the ability to append what was in the buffer to a recording so if you got 10 minutes in and decided to record, it would get the whole show and not just from the point you hit "Record." I suspect it would have been a trivial feature to add, but was just an oversight on the part of Microsoft.

Wow. I had just assumed everything had that feature. That's a huge drawback for WMC.

I doubt that is an oversight. It is probably most requested feature ever since WMC started to support TV recording. I suspect it has to do with Microsoft refuses to pay TiVo royalty for such feature.

Ahhh that would explain it too.

Just out of curiosity, has anybody tried rewinding back to the beginning of the program, then hitting "record" to see if it will catch the whole show? (obviously not as good as the STB feature, but at least it's a workaround of sorts)

I heard some have tried that rewinding trick and worked. But I personally don't have the same luck.

Did not work for me either.

As a follow up to my earlier post, I did a little poking around the interwebs, and it turns out that the fine folks at Hitachi made a Filter Driver, that can be loaded (in place of the standard USB removable storage driver) that will allow removable drives to show up as Fixed disks (and thus configurable for Live TV Buffer/Recorded TV Storage)

The bad news is they didn't release a 64 bit version.

The good news is, some kind sole managed to recompile it for 64bit systems.

The bad news is, it's an unsigned driver.

The good news, is you can still force Windows to install an unsigned driver.

The bad news is it's a bit of a PITA.

The good news is, it comes with a free frozen yogurt....

But for ~$15 you can stick 32GB worth of recording buffer into the back of your NUC, and not have to worry about reinstalling your OS if it wears out.

USB sticks are pretty slow to write to... does that matter?

Yes, it does matter, so one should shop accordingly, but there are plenty that are easily fast enough to handle 4 or 6 tuners. (A handful of USB 3.0 models can outperform a 7200rpm disk drive)

But that is a good point you bring up.

When I was shopping for USB sticks for my Xbox, I tried many and found out only handful of USB sticks out there are actually faster enough for pass the Xbox 360's requirement for write speed. Majority of cheap USB sticks are just junks that has very slow write speed although read speeds are usually pretty good.

I believe I amended an earlier post to indicate that I plan on using an external USB enclosure with a standard 2.5" laptop drive for the Recorded TV folder and the live TV buffer. What's strange is what prompted me to do this. I installed Windows 7 64-bit and all drivers, updates, XBMC, and a few miscellaneous apps onto a MyDigital 64GB mSATA drive for the 1st NUC. I was able to configure the Recorded TV folder on the drive and append it with the one from my primary HTPC that's mapped to the NUC so I could share recordings.

I purchased a 64GB Plextor mSATA drive to use in the 2nd NUC and cloned it from the MyDigital drive. The drives show up as the same size under Disk Manager in Windows, but when I went to set up the Recorded TV folder on the Plextor, WMC informed me that I needed a minimum of 30GB of available space in order to set up the Recorded TV folder and that I was about 3GB short. Aside from the addition of the Thunderbolt ethernet driver, which is almost negligible in size, the two drives contain exactly the same amount of data and display the same available space in Disk Manager. I ended up attaching an external USB adapter with a standard 3.5" hard drive for temporary use as the Recorded TV location.

Was there any buffered recordings or other "remnants" from the 1st NUC on the cloned drive? There could be a buffer file in there just clogging up a few gigs, or maybe power management is setup differently, and you have a hibernation file?

I don't believe so, but I don't recall if I ever checked. In any case, wouldn't they be deleted if the NUC was rebooted?

I would think so, but stranger things have happened.

Only other thing I can think of is the partitioning/formatting of the new drive went wonky and the file sizes of your tiny files effectively doubled. I really don't know if that's an issue these days, but I remember, running into a few spots copying drives, and the cluster sized changed, so that the same files took up more space on a bigger drive than they did on a smaller drive.

I decided to do a little more investigating about the possible cause for the lack of space on the C: drive for the Recorded TV folder but I drew a blank. I looked at the available space and it was showing 29.4GB. I got an idea so I created a RecordedTV folder on the C: drive and added it to the Media Libraries for Recorded TV. I then went into the Recorder Storage setup and changed the default location to the folder on the C: drive I just created. Previously, I had been unable to point to any drive in this setup until I added the external drive. For some reason it was now listed as a viable location. Once I did that I went back in the Media Libraries for Recorded TV and deleted the external drive. Now it just points to the C: drive for Recorded TV and I have physically disconnected the external drive.

I guess this was just another weird feature from Microsoft that we didn't have to pay extra for. rolleyes.gif
