I can help with that. Right now, the most reliable way to watch a Rockets vs Mavericks game depends on your location and current broadcast rights, but here are common options you can check:

• local TV and regional sports networks: In the U.S., in-market games are often shown on regional networks. Check listings for channels covering your area (for example, Space City networks or their local affiliates in Houston), as well as possible national feeds.
• streaming services and fronthaul options: In-market streams are typically available on platforms like FuboTV, Sling TV, YouTube TV, or NBA League Pass with blackout rules considered. Check if the game is included in a free trial or any promotional offer.
• official team and league sources: The Rockets and Mavericks’ official sites or the NBA app often provide viewing details, start times, and legitimate streaming options for your region.
• alternative viewing: If you’re traveling or outside the primary market, NBA League Pass or appropriate regional sports networks may offer streams, sometimes with blackout restrictions.

If you’d like, tell me your country/region and whether you prefer TV, streaming, or both, and I’ll give you a precise, up-to-date option list with start times and channel names.
