An HTPC on the cheap with GB-PVR

[Guest]

All this is great if you can get free listings (EPG). Now that Zap2It, Schedules Direct ($20/yr.) & others charge, is there another service that will work for generating free XMLTV listings (for Canada)?

I have been getting frustrated trying & opted to use a trial version of Beyond TV but would like to try GB-PVR &/or Media Portal after reading rave reviews. However, the key it seems is a free & accessible EPG.
