OK I went to Fry's after dinner. Couldn't find a single 820 microfarad capacitor! But I did pick up a couple of 2200 ones (always nice to have a spare). The only ones they had were rated 25V, 105°C, and were $2 each. They weren't Panasonic low-ESR ones but they fit perfectly.
Replacing C34 has the DVR+ at least limping along now. It's not freezing and locking up like before. But I'm seeing quite a few glitches that look like a bad signal (but aren't), so I'm afraid C242 is going to need replacing too, as soon as I can get a-hold of an 820.
Also replaced the 250GB drive with a 750GB Seagate Barracuda drive. Always nice to have lots of room for recordings.
