Did this happen soon after the 6.2 upgrade made by Tivo? This is what happened the day after my unit was upgraded to 6.2 (about 3 weeks ago).
First, I'd like to apologize for starting a new thread, but I did search these forums and found no similar issue.
The closest was the thread "Hanging when skipping fwd or back," but after reading the entire thread (ouch :rolleyes: ) I don't think it relates to my issue.
My problem is that since installing the PTVUpgrade in my Series 1 Sony SAT-T60 I have twice had the system completely stop responding to controls. Completely. The remote doesn't work, the front panel controls don't work and, of course, it won't respond to telnet or FTP or TiVoWeb.
The system will, however, continue playback of the recording I was watching. At the end of the playback, it's locked. The only way to proceed at that point is to unplug the unit and wait 20 minutes for the reboot.
The only hacks I have installed are the PTVUpgrade itself, TiVoNet, CacheCard and TivoWeb.
I, too, am having the exact same problem with a SAT-T60 Series 1 TiVo. My software version is 3.1.0c2-01-1-011. I purchased the unit on ebay from someone who did the install himself. He got the DIY kit with a new harddrive, the cachecard, and 512MB RAM. The unit was working fine for a few days and now it is locking up about twice a day. When it locks up shows stop recording and eventually it will reboot itself. The only difference from the other poster is that I can use telnet and ftp to get in, nothing else seems to work.
Most common cause of a problem like this is a defective hard drive. Could also be a loose cable, loose networking card, or a network that is not properly secured (if you've got lots of open ports on your router, port scans from outside your network can cause your TiVo to freeze).
I am having what sounds like the same problem on my Philips Series 1 Standalone. The symptoms are exactly as described in PTCartman's initial post.
Since I would like to access my TiVo during an extended trip, the only workaround I can think of is to install a remote control relay to unplug and restart the TiVo when it becomes unresponsive.
If someone can suggest a better solution, I would be grateful..
I'd recommend you look into gotomydvr; its more secure, doesn't require any router configuration at all, and currently, its FREE.
