That is correct, TitanTV was only mentioned because of the amount of information that it makes available.
If you are into OTA recordings you may want to enhance your options with a ATSC tuner card. My choice is the MIT MDP-120 or MDP-130, unfortunately they have been discontinued. They can still be found at some outlets. Kei Clark (Digital Connection) has the MDP-130 for $89.00 (that is a great price, I paid more than $250.00 for each of my MDP-120s), there is a daughter card available but I do not see it listed at DC. The daughter card has a DVI output that can be used with video devices that has a DVI and/or HDMI input(s). Click here for info. If you are interested there are some threads on these devices in the HTPC section.
On average I record about 7 hours worth of shows weekly, this I do on my office PC. These shows are edited with HDTV2MPEG, saved to a USB 160GB pocket drive (2.5") and played back on the HTPC which is connected to the JVC projector. The MDP has a TitanTV helper app, I just select the program in TitanTV and click the Record button which pops up the app (see below). I may add to the program name to include the episode title or if two shows are back-to-back I will set the record length to 2 hours (I usually start recording 1 minute till the hour and set the duration for 1 hour and 2 minutes for a 1 hour show).
I am looking into getting a M-6620N for the better half so she can record her daytime shows on it. She could also use it to playback shows from the pocket drive or from the other 2TB worth of hard drives we have.
