Yes, originally DirecTV boxes were sold at retail, branded by whatever company made them; RCA, Sony, Toshiba, Samsung, etc., and ran software unique to each. Because none of the DBS systems at the time had the capacity or capability to provide local HD stations, these units included a Digital TV OTA tuner. The box integrated the programming guide info for the DirecTV channels with the PSIP from the local Digital TV channels. A few years ago DirecTV changed their system so that all boxes are DirecTV branded, use the exact same software, and local HD channels are carried on the system. The first few generations of DirecTV branded boxes also had Digital TV tuners built in, but current units do not.
The VOOM box is older (I think) and does not display either program info or time. It has an obvious conflict with TVGOS, which causes it to reboot when tuned to a station carrying TVGOS, like CBS previously was.
The Voom box is a little older than the Samsung. Their boxes worked like the other DBS providers, getting local HD from a built in Digital TV tuner that was integrated with the channels from Voom. It's always been a mystery why TVGOS crashed the Voom boxes, but (IIRC) since the problem started after Voom went out of business in 2005, and comparatively so few boxes were in the market, little effort was made to fix the problem.
Again, I hate to say it but once WCBS re-adds TVGOS, the Voom box will probably crash when tuned to WCBS. I hope by some miracle I'm wrong.
Thanks for the PSIP info you provided. Although the Samsung box does display the current program and some of the upcoming ones, it tends to only give the next 3 hours or so.
That can vary from station to station, depending on how much PSIP data they load, and from box to box, depending on how the box handles PSIP. Another issue is the time setting. Because each channel can have a different time, the box can change time as it changes channels. The difference time can vary is unlimited; from a second to minutes to hours.
