RPi3 TVH 4.2 HDHR_Connect PVR problems

I've been lurking in the shadows reading the forum posts and I'm so close to getting everything working, I can feel it! But I'm running into a recording issue. First, here's my setup:
I've got a Raspberry Pi 3 running LibreElec 7.0.2, TVHeadend Backend 4.2, HDHomerun Connect TV Tuner, Zap2XML 0.4 EPG all running on a Sandisk Ultra Class 10 32GB microSD card. I live in the U.S. so I had to manually enter my MUX frequencies since the ATSC-T split messed up the scanning profiles. I finally go the Zap2XML EPG working and I have attempted 3 different scheduled recordings over the last few days. Every recording has gone to the Failed Recordings tab because of too many errors (over 230,000). I've downloaded the recordings to my PC and they have a lot of frozen frames and major pixelizing. When I play live tv on the RPi3 itself, there is none of that.

Am I getting all these errors because I'm trying to record to the SD Card? Would it help to have a powered USB hub with an external hard drive to record to?

I've been trying to get a PVR solution to work ever since I cut the cord a few years back and I'm really trying to avoid buying the $400 Tivo solution since I feel like I can make this work.

Any help would be greatly appreciated!

I have pretty much the same setup as you except I am running the newest alpha and am using an external harddrive. This seems to work with no problems. When I was first configuring everything, there was a time when I recorded to the sdcard and it seemed to be working properly.

How did you mount the hard drive. Do you use a powered USB hub or plug it straight into the RPi? Are there any special steps to get LibreElec to recognize the drive?

Sorry for the delay in responding. I do use a powered hub. LibreElec will see the drive and mount it on bootup.

So, I have a 128GB USB 3.0 flash drive plugged into one of the USB ports but it only helps a little. I've found that I am actually getting a poor connection between the RPi and the HDHR Connect (digital noise and freeze frames). I'm wondering if this is because I'm using a wireless adapter on the HDHR Connect and connecting wirelessly with the RPi as well. I'm going to try to connect the two to the router to see if it helps. If not, I think I may have run this to the ground and I'm not using the right hardware to do what I'm trying to accomplish.
