Here's an example from my DTVpal DVR.  Only 49-1 has TVGOS data, all the rest is from PSIP (easily verificable by going forward a day or so - all the TVGOS channels have 8 days worth).  A couple of interesting points on this shot:

- Sun TV has program details in some of their shows - I don't think any other Toronto broadcaster has done this
- 49-2 has slightly different details than 49-1 - that's because 49-1 is from TVGOS and 49-2 is from PSIP.

As you can see, it's really difficult to set up a timer to record for Global, or CITY, etc. because of their useless program data in PSIP and that it won't pick up TVGOS for them either.
