My LST-3410A arrived a few days ago and I've had only a little time to play with it so far.
With the 300GB Maxtor drive recommended by Value Electronics, the unit shows "31:55" as the HD recording capacity when empty, which is comfortable even though not huge.
I was pleased to discover that my cable system (Comcast of Union County, NJ) does provide a number of unscrambled digital channels that the 3410A is able to tune.
But there's a big problem.
My cable system is HRC, and always has been for as long as I've had devices that cared about tuning the analog cable channels. When I tell the LG's "EZ Scan" to tune cable as HRC, it finds all the analog cable channels but no digital channels at all.
On a hunch I had it scan as STD instead of HRC. This time it found several digital channels but none of the analog ones.
If I leave the setting (i.e., the last "EZ Scan" done) on HRC, the unit can tune all the analog cable channels perfectly, and receives all the guide information for the cable system, but is unable to tune any of the QAM digitals. It finds none of them in a scan, nor does it ever find them if I patiently try to tune them manually using the "Ch Edit" menu.
If I leave the setting on STD, it finds the cable digitals (some with difficulty--there may be a signal strength issue) but no analog channels, and in particular there's no program guide because (presumably) the Gemstar data is sent on one of the analog channels that I can't receive.
It seems that I have to choose between using this unit for manual-only recordings of digital channels (OTA and cable), or using it as a recorder for analog cable and digital OTA together with the program guide. There doesn't seem to be any way of having the unit use HRC for analog cable but STD for digital cable.
The HD recording capability coupled with 1394 makes this unit invaluable, so I don't want to give it up. But as a PVR it has deficiencies already described at length in this thread, and it has so many lame idiosyncrasies that it's disappointing and slightly creepy.
